Linking Work Self-Efficacy To Change-Supportive Behavior Through Career Adaptability And Person–Organization Fit Under Proactive Behavior Conditions

Social Cognitive Theory

Social Cognitive Theory (SCT) provides a framework for understanding human behavior as the product of dynamic, reciprocal interactions among personal attributes, environmental conditions, and behavioral patterns (Bandura, 1989; Wang et al., 2019). When applied to the context of employee adaptation during organizational transitions, SCT highlights the role of observational learning encompassing attentional focus, information retention, behavioral reproduction, and motivational reinforcement as a mechanism through which individuals internalize new organizational norms and develop the confidence to operate within them (Wood & Bandura, 1989). Central to this theory is the concept of self-efficacy: the degree to which individuals trust their own capability to execute required tasks, shaped by accumulated experience, available environmental support, and cognitive processing, collectively influencing whether adaptation to novel circumstances succeeds or falters.

Career Construction Theory

Career Construction Theory (CCT) offers a comprehensive framework for understanding how individuals actively shape their professional trajectories. Building upon earlier career development models (Hackett & Lent, 1992), CCT is widely regarded as one of the most integrative approaches in career research. Its central proposition is that individuals construct their careers by adapting their personality characteristics and self-concepts to the sequential demands of work roles a process encapsulated in the concept of Career Adaptability (Savickas, 2006). Savickas (2013) further elaborates that career construction counseling can foster self-concept development by helping individuals discover and articulate the subjective meaning embedded in their career experiences. The Career Construction Model of Adaptation, as depicted in Figure 1, outlines four progressive stages: Adaptive Readiness, which reflects dispositional willingness to engage with career challenges; Adaptability Resources, representing the psychosocial competencies individuals bring to transitions; Adapting Responses, describing the specific coping strategies employed during change; and Adaptation Results, capturing the outcomes of the adaptive process (Savickas, 2005, 2013; Savickas & Porfeli, 2012; Savickas et al., 2009). The Career Construction Model of Adaptation, as depicted in Figure 1, outlines four progressive stages: Adaptive Readiness, which reflects dispositional willingness to engage with career challenges; Adaptability Resources, representing the psychosocial competencies individuals bring to transitions; Adapting Responses, describing the specific coping strategies employed during change; and Adaptation Results, capturing the outcomes of the adaptive process (Savickas, 2005, 2013; Savickas & Porfeli, 2012; Savickas et al., 2009).

Work Self-Efficacy

Self-efficacy, as conceptualized by Bandura (1997), refers to an individual’s conviction regarding their ability to organize and execute the actions required to accomplish specific tasks. This belief is shaped through cognitive evaluation of one’s capabilities in interaction with environmental demands (Gufron & Risnawati, 2016; Sebayang, 2017; Renaningtyas, 2017). Research has established that self-efficacy meaningfully influences motivational processes, job performance, work engagement, and the capacity to adapt performance standards in response to changing conditions (Bandura, 1989; Wijayati, 2014; Barbaranelli et al., 2018; Tian et al., 2019; Abun et al., 2021; Çetin & Aşkun, 2018). Four principal sources contribute to the formation of self-efficacy: mastery experiences, vicarious learning through observing others, social persuasion, and the interpretation of physiological and emotional states (Bandura, 1989). Work Self-Efficacy, as a domain-specific application, captures employees’ confidence in managing their professional activities. It reflects dimensions including self-regulation, adaptability, interpersonal effectiveness, and personal initiative, operationalized through indicators such as the ability to meet performance targets, adhere to deadlines, acquire new methodologies, collaborate effectively, and sustain productive working relationships (Peng et al., 2021; Pethe et al., 2000; Abun et al., 2023). Research has established that self-efficacy meaningfully influences motivational processes, job performance, work engagement, career aspirations, and the capacity to adapt performance standards in response to changing conditions (Bandura et al., 2001; Barbaranelli et al., 2018; Tian et al., 2019; Abun et al., 2021; Çetin & Aşkun, 2018).

Person-Organization Fit

Person-Organization Fit (P-O Fit) describes the degree of compatibility between an employee and the organization in which they work. This compatibility is manifested through shared values, aligned objectives, and the reciprocal fulfillment of needs (Ahmadi et al., 2014; Edwards & Bilsberry, 2010). Kristof (1996, as cited in Bakrie et al., 2014) conceptualizes P-O Fit as a condition that emerges when either the individual or the organization satisfies the requirements of the other, when both share fundamental characteristics, or when both conditions are simultaneously present. This conceptualization encompasses four dimensions: congruence between organizational culture and individual personality, alignment of goals, satisfaction of employee needs, and correspondence between personal and organizational values (Astuti, 2010). Organizations benefit from high P-O Fit through enhanced employee attitudes including greater satisfaction, loyalty, and cooperative behavior as well as improved performance outcomes and reduced turnover. Additionally, strong fit contributes to the reinforcement of organizational culture and the quality of work design (Bowen, as cited in Afianty, 2005). The present study measures P-O Fit using Kristof’s indicators of value congruence, goal congruence, need fulfillment, and culture-personality alignment (Astuti, 2010).

Career Adaptability

Career Adaptability (CA) denotes the psychosocial capacity that enables individuals to navigate career-related changes and role transitions effectively (Savickas, 2005). It can also be understood as the readiness to anticipate and manage unforeseen shifts in career plans (Rottinghaus et al., 2005; Bimrose et al., 2011). The present study adopts Savickas’ (2005) framework because of its theoretical comprehensiveness and extensive empirical application across diverse research contexts (Nirwani et al., 2022; Sisca & Gunawan, 2015; Rahmania & Abidin, 2022). Savickas’ model identifies four core dimensions: concern (thinking about one’s professional future), control (taking responsibility for career decisions), curiosity (exploring possibilities and alternative paths), and confidence (maintaining self-assurance in the face of obstacles). These dimensions are influenced by demographic and experiential factors including age, gender, socioeconomic status, work tenure, educational background, and family context (Gunawan, 2014).

Change Supportive Behavior

The capacity of organizations to implement change successfully depends critically on the reactions and readiness of those who are expected to enact it (Choi & Ruona, 2011; Oreg et al., 2011; Armenakis et al., 1993). Change Supportive Behavior encompasses the active participation and genuine commitment of employees to engage in actions consistent with organizational change objectives, though the theoretical literature on this specific construct remains relatively underdeveloped compared to broader change readiness research (Kim et al., 2011; Herscovitch, 1999; Lamm & Gordon, 2010). In operational terms, Change Supportive Behavior involves accepting proposed changes, implementing new procedures, and actively championing the change agenda within the organization, representing a form of constructive employee engagement that extends beyond mere compliance (Armenakis et al., 1993; Herscovitch & Meyer, 2002; Orth, 2002; Stevens, 2013).

Proactive Behavior

Proactive Behavior is becoming increasingly important for organizational success because work is now more decentralized and dynamic, so companies depend on individual initiative to identify and solve problems (Frese et al., 1997); individuals with a proactive attitude tend to actively bring about change in their environment, while those who are less proactive are more reactive to their work (Bateman & Crant, 1993). Task delegation also needs to be well regulated so that employees are able to perform their jobs optimally (Tistasari et al., 2023). Thus, Proactive Behavior can be understood as the behavior of individuals in creating positive changes in the work environment through more effective and efficient task completion, accompanied by a commitment to continue moving forward and a readiness to face challenges. In the context of this study, proactive behavior is reflected in the CIVIL SERVANTS of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia who strive to adapt to the demands and dynamics of their new organization, while also functioning as mediators who encourage superior performance and long-term career development. Proactive Behavior is becoming increasingly important for organizational success because work is now more decentralized and dynamic, so companies depend on individual initiative to identify and solve problems (Frese et al., 1997). Individuals with proactive personalities tend to actively influence their environment and initiate constructive changes rather than merely reacting to workplace situations (Crant, 1993; Bateman & Crant, 1993).

H1. Work Self-Efficacy on Person-Organization Fit

Work Self-Efficacy encourages individuals to continue learning and adapting to job demands, thereby improving the fit between individuals and the organizational environment (Thompson et al., 2016; Edwards et al., 1998). In the context of the CIVIL SERVICE of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia, high self-confidence has been shown to facilitate their adaptation to new tasks after the separation of agencies, in line with Social Cognitive Theory and findings (Iddrisu & Adam, 2024; AKKOÇ & TÜRE, 2020).

H2. Work Self-Efficacy on Person-Organization Fit Moderated by Proactive Behavior

Proactive behavior strengthens the influence of Work Self-Efficacy on an individual’s ability to adapt to organizational culture, as explained in Social Cognitive Theory (Bandura, 1986; Klein et al., 2025). In the context of the CIVIL SERVICE of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia, being proactive in understanding new tasks and environments facilitates adaptation, thereby strengthening the relationship between the two (Matsuo, 2024; (Robert) et al., 2025).

H3. Person-Organization Fit on Career Adaptability

Individual-organization fit encourages increased commitment and motivation to develop one’s career (Gratiana et al., 2024; Bocciardi et al., 2017). From the perspective of Career Construction Theory and Social Cognitive Theory, this alignment facilitates employees of the INDONESIAN CIVIL SERVICE Ministry of Political and Security Affairs to emulate successful behaviors and adapt to increasingly complex career demands (Savickas, 2005; Eissa & Lester, 2025).

H4. Career Adaptability towards Change Supportive Behavior

Career adaptability makes employees more prepared to support organizational change because they understand the benefits of change for their career development (Kim et al., 2011; Safavi & Bouzari, 2019). Cognitively, employees with high adaptability have a positive perception of change and thus tend to exhibit behavior that supports organizational policies (Wang, 2015).

H5. Person-Organization Fit on Change Supportive Behavior

Employees who feel compatible with organizational values and culture are more likely to accept and support change because they feel comfortable and aligned in their work (Krisna & Adnyani, 2021). This alignment is reinforced by elements of Social Cognitive Theory, which states that individuals, behavior, and the environment influence each other in forming positive motivation toward change (Nguyen & Nguyen, 2024; Astuti & Amir, 2023).

H6. Person-Organization Fit on Change Supportive Behavior mediated by Career Adaptability

Individual adjustment to the organization over a period of time increases career adaptability, which in turn strengthens attitudes supportive of change (O’Reilly et al., 1991; Katsaros & Tsirikas, 2022). When personal values align with organizational values, career adaptability helps employees demonstrate loyalty through support for change policies (Savickas, 2005; Wijiati & Priyono, 2022).

Conceptual Framework of the Study

The conceptual framework of this study is presented in Figure 2. The model depicts Work Self-Efficacy as the exogenous variable, Person-Organization Fit as both a dependent and mediating construct, Career Adaptability as a mediating variable, Change Supportive Behavior as the primary outcome, and Proactive Behavior as a moderating variable on the Work Self-Efficacy–Person-Organization Fit path.

Research Hypotheses

Based on the conceptual framework above, the following hypotheses can be derived.

Research Design and Participants

This study adopted a quantitative research design with a cross-sectional survey approach, aimed at testing hypothesized relationships through measurable data and statistical analysis (Hair et al., 2008). Survey methodology was selected as the primary data collection strategy to capture respondents’ beliefs, perceptions, and behavioral orientations (Neuman, 2014). The population comprised civil servants of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia who had served for less than three years, specifically targeting their behavioral responses to organizational change following the ministerial separation. From this population of 184 civil servants meeting the inclusion criteria, all were invited to participate. Respondent selection followed a two-stage procedure: purposive sampling was first applied to identify civil servants directly affected by the organizational restructuring (Sugiyono, 2017), followed by simple random sampling to select participants from within this eligible group. Primary data were collected through observation, semi-structured interviews, and a self-administered Likert-scale questionnaire, while secondary data were obtained from official institutional documents (Creswell, 2009).

Measurement and Data Analysis

Data analysis employed descriptive statistics and Structural Equation Modeling–Partial Least Squares (SEM-PLS) using SmartPLS 4.0. The measurement model (outer model) was evaluated through indicator reliability (outer loadings >0.708), composite reliability (CR ≥ 0.70), internal consistency (Cronbach’s alpha ≥0.60), convergent validity (AVE > 0.50), and discriminant validity using the Fornell-Larcker criterion (Hair et al., 2017; Fornell & Larcker, 1981). The structural model (inner model) was assessed using the coefficient of determination (R²), predictive relevance (Q²), effect size (f²), and the variance inflation factor (VIF < 5) to evaluate collinearity (Hair et al., 2014, 2019a). Hypothesis testing employed bootstrapping with 5,000 subsamples, applying a significance threshold of p < 0.05 and a critical t-value of 1.96. Mediation analysis followed the procedure described by Baron and Kenny (1986), supplemented by the approach of Hayes (2009) and Preacher and Hayes (2008), evaluating the significance of both direct and indirect pathways. Through these stages, the study is expected to provide empirical evidence regarding the influence of Work Self-Efficacy, Proactive Behavior, Person–Organization Fit, and Career Adaptability on Change Supportive Behavior among Civil Servants in the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia. Written informed consent was obtained from all participants prior to data collection. Participants received an information sheet explaining the purpose of the study, the voluntary nature of participation, the anonymity of responses, and their right to withdraw at any time without consequences. For questionnaires distributed online, participants provided consent by selecting an “I agree to participate” option before accessing the survey items. No identifying information was collected from participants.

Results

Structural Equation Model Measurement

The reflective measurement model is a measurement model that assumes that indicators are manifestations of constructs.

Outer Loading Measurement

The measurement model was first assessed by examining outer loading values to determine indicator reliability. Items with outer loadings exceeding 0.708 were retained, as they indicate that the construct explains more than 50% of the indicator variance (Hair et al., 2019a). The results for exogenous and moderator variables are presented in Table 1.

Based on Table 1 above, it can be seen that the outer loading value in the work self ecfficacy variable there are several items that are omitted because to meet the CR value <0.95. As for some of the items that were removed, they were WSE2, WSE4, WSE5, WSE7, WSE8, WSE9, WSE10, all of these items were removed because they had an outer loading value of <0.708. While the others have an outer loading value above 0.708. In the person organization fit (POF) construct, almost all items have an outer loading value above 0.708, meaning that all constructs can explain more than 50% of the variance of the indicator. However, there is only 1 item, namely POF6, which has a value of <0.708 so it must be eliminated because the item is considered unable to explain the variance of the indicator. For the proactive behavior (PB) construct, there are 2 items that must be eliminated, namely PB1 and PB 4 while the rest, namely PB 2 and PB 3, are considered to be able to explain more than 50% of the variance of the indicator because it has an outer loading value of >0.708. the last is for the Change supportive behavuour (CSB) construct, all items are considered to be able to explain the variance of the indicator because they have a value above 0.708. where the highest outer lading value is in item CSB 1 of 0.898.

Based on the Table 2, it can be seen that the Career adaptability (CA) construct has 4 dimensions, including Concern (CO), Control (CN), Curiosity (CU) and Confidence (CF) and each dimension has 6 indicators. Overall the outer loading value of this dimension is more than 0.708 which means that the construct is able to explain more than 50% of the variance of the indicator. In the CO dimension, there are 2 items or indicators that are omitted, namely CO2 and CO6 because the value is below 0.708 where the highest outer loading value is 0.889 and the lowest is 0.834 while for the CN dimension there is 1 item that is omitted, namely CN3, the highest outer loading value is 0.830 and the lowest is 0.760 for the CU dimension, there are several items that are omitted, namely CU1, CU3 and CU4 because the outer loading value is below 0.708. The highest outer loading value is 0.855 and the lowest is 0.830. The last one is in the CF dimension where the highest outer loading value is 0.896 and the lowest is 0.834 and there is 1 item that is omitted, namely in CF2. The outer loading value in the Career adaptability (CA) construct has a value above 0.708. This shows that the construct is able to explain more than 50% of the variance of the indicator.

Internal Consistency Reliability

Assessment of the reliability of internal consistency using Joreskog’s composite reliability (Hair et al., 2019b). Here are the CR and Cronbach alpha values of the construct variable. The CA dimensions also demonstrated adequate reliability: Concern (α = 0.873, CR = 0.913), Control (α = 0.876, CR = 0.910), Curiosity (α = 0.802, CR = 0.883), and Confidence (α = 0.917, CR = 0.937), as shown in Table 3.

Composite reliability and Cronbach’s alpha values for all constructs fell within the acceptable range (above 0.70 and below 0.95), confirming internal consistency without redundancy. WSE achieved values of 0.829 (α) and 0.898 (CR); POF achieved 0.928 and 0.942; PB achieved 0.739 and 0.884; and CSB achieved 0.807 and 0.886. The CA dimensions also demonstrated adequate reliability: Concern (α = 0.873, CR = 0.913), Control (α = 0.876, CR = 0.910), Curiosity (α = 0.802, CR = 0.883), and Confidence (α = 0.917, CR = 0.937), as shown in Table 3.

Convergence Validity

The next step to performing a measurement model is convergent validity. An acceptable Average Variance Extracted (AVE) must have a value of >0.50 which means that the construct is able to explain at least 50% of the variance of the item (Fornel & Larcker, 1981). If the AVE value is <0.5, the item with the lowest outer loading can be removed. The highest AVE was observed for Proactive Behavior (0.793), followed by Confidence (0.750), Work Self-Efficacy (0.745), Concern (0.724), Change Supportive Behavior (0.722), Curiosity (0.716), Person-Organization Fit (0.699), and Control (0.670), as reported in Table 4.

All constructs have an AVE value of >0.5, indicating that the items in each variable are able to explain the variation and form a unit of the construct. The highest AVE score was found in Proactive Behavior (0.793), followed by Work Self-Efficacy (0.745), Change Supportive Behavior (0.722), and Person-Organization Fit (0.699), while for the Career Adaptability dimension, the highest AVE score was found in confidence (0.750) compared to concern (0.724), control (0.670), and curiosity (0.716). These results ensure that the indicators in each construct are valid and capable of explaining the significant percentage of item variance.

Discriminatory Validity

The purpose of discriminant validity testing is to ensure that each concept of each latent model has a difference with other latent variables. Where the construct in question has a higher value compared to other constructs. In this study, the discriminant validity test used the Fornell-Larcker criteria.

The Fornell-Larcker criterion was applied to assess discriminant validity. As shown in Table 5, the square root of each construct’s AVE (presented on the diagonal) exceeded all inter-construct correlations in the corresponding row and column, confirming that each construct is empirically distinct from the others. For instance, Career Adaptability’s diagonal value (0.908) exceeded its highest correlation with other constructs, and similarly for all remaining variables.

Structural Model Testing

Structural model measurements in reflective models include the following, including 1) multicoloniarity measurement, 2) R2 value measurement, 3) effect size (f2) value measurement, 4) predictive relevance (Q2) value measurement, and 5) hypothesis testing. The first step in the structural model test is a multicollinearity test to determine whether or not research data is biased on independent variables. The criterion used is that the inner value of VIF should not be ≥5 (Hair et al., 2014). The results were that the VIF value for the variables of work self efficacy, proactiver behaviour, person organization fit and career adaptability was 3,012; 2.040; 2.945; 2.945;. The value is still below 5 which means that multicollinearity does not occur (Hair et al., 2014). Furthermore, structural testing of the model was used for the relationship between the construct, significance value and R square of the research model. The R-square value can be used to assess the influence of a particular independent variable on a dependent variable. The estimated value of R-square can be seen in the following table.

Table 6 presents R² and Q² values for the endogenous constructs. Career Adaptability (R² = 0.660, Q² = 0.497), Change Supportive Behavior (R² = 0.549, Q² = 0.388), and Person-Organization Fit (R² = 0.685, Q² = 0.541) all fall within the moderate explanatory range (Hair et al., 2014). The Q² values, obtained through blindfolding, substantially exceed zero, demonstrating that the model possesses meaningful predictive relevance for all three endogenous constructs (Sarstedt et al., 2014; Hair et al., 2017). Predictive analysis using Q² through blindfolding showed strong values for Career Adaptability (Q² = 0.497), Change Supportive Behaviour (Q² = 0.388), and Person-Organization Fit (Q² = 0.541), meaning that the model has high predictive relevance (Sarstedt et al., 2014; Hair et al., 2017).

Analysis of direct and indirect influences

Direct impact analysis

This analysis aims to test the direct influence between dependent and independent variables that refer to the hypothesis that has been proposed. The testing process was carried out using the bootstrapping function on SmartPLS 4.0. The hypothesis is accepted when the significance level is less than 0.05 or the t-value exceeds its critical value (Hair et al., 2014). The statistical t-value for the significance level of 5% was 1.96. The results of the hypothesis testing that test the direct effect can be seen in the table below.

Bootstrapping results for the direct effect hypotheses are presented in Table 7. Three of the four direct-effect hypotheses were supported. Work Self-Efficacy significantly predicted Person-Organization Fit (H1: β = 0.364, t = 4.204, p < 0.001). Person-Organization Fit significantly predicted Career Adaptability (H3: β = 0.813, t = 21.383, p < 0.001). Person-Organization Fit also significantly predicted Change Supportive Behavior (H5: β = 0.857, t = 4.403, p < 0.001). However, Career Adaptability did not significantly predict Change Supportive Behavior (H4: β = 0.181, t = 1.240, p = 0.216), and this hypothesis was rejected.

As shown in Table 8, Proactive Behavior significantly moderated the relationship between Work Self-Efficacy and Person-Organization Fit (H2: β = 0.421, t = 5.425, p < 0.001), confirming its role as a positive moderator. In contrast, Career Adaptability did not significantly mediate the relationship between Person-Organization Fit and Change Supportive Behavior (H6: β = 0.147, t = 1.252, p = 0.211), and this mediation hypothesis was rejected. The complete structural model with path coefficients and significance levels from the SEM-PLS bootstrapping analysis is presented in Figure 3.

Hypothesis Testing Results

The discussion carried out in this study is based on theories related to the research and then associated with empirical studies or previous research. This was done to assist in confirming support related to hypothesis testing in this study. So that the results of this research are expected to have a significant theoretical contribution and can be used as a connecting bridge for future researchers.

The Effect of Work Self Efficacy on Person Organization Fit

The results of the analysis showed that Work Self-Efficacy had a significant effect on Person-Organization Fit in employees of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia (t = 4.204 > 1.97; p = 0.000), confirming that employees’ confidence in completing tasks determines their ability to adapt to the new environment. The separation of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia into the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia and the Coordinating Ministry for Law, Human Rights, Immigration, and Corrections of the Republic of Indonesia requires employees to adjust to the new work and environment, which is accelerated through four factors of self-efficacy according to Bandura (1989), namely the achievement of goals, performance, observation of others, and cognitive conditions. A quick adaptation strategy includes building rapport with superiors, being professional towards clients or strategic partners, and the ability to work in a team to complete tasks effectively.

The role of proactive behavior as a moderation variable between work self efficacy and person organization fit.

Proactive Behaviour played a significant role as a moderator in the effect of Work Self-Efficacy on Person-Organization Fit (t = 5.425 > 1.97; p = 0.000), suggesting that proactive attitudes strengthened the relationship. Proactive attitudes, such as building good relationships with their bosses and being open to direction, encourage employees to take the initiative and express innovative ideas in a psychologically safe work environment (Robert et al., 2025). Proactive actualization of employees of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia · is reflected in the ability to find solutions to work problems, for example collecting and analyzing additional data to estimate security conditions in a particular region, so that solutions are executed procedurally.

Person organization fit has a significant effect on career adaptability

Based on the analysis, Person-Organization Fit has a significant effect on the Career Adaptability of employees of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia · (t = 21.383 > 1.97; p = 0.000), showing that employee compatibility with the agency accelerates career adaptation. This match helps employees understand the character of the agency, follow the direction of the leadership, and prepare themselves for a higher career path, so that they can make a positive contribution to the organization. Previous research has also emphasized that emotional attachment and positive perceptions of the psychological climate, as well as a clear organizational structure, are important factors in employee engagement and career development (Ojokuku et al., 2022).

Career adaptability has a significant effect on change supportive behaviour

Career Adaptability does not have a significant effect on Change Supportive Behaviour in employees of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia · (t = 1.24 < 1.97; p = 0.216), suggesting that career adaptation is not a direct indicator of support for change. Although employees adjust to new tasks and career paths, this is more of a personal responsibility and preparation for the future than a form of active participation in organizational change. Employees still need to build confidence, curiosity, and complete tasks efficiently, so as to create a professional and characterful organizational climate even though they do not directly support change.

Individual organizational fit to change and supportive behavior

Person-Organization Fit has a significant effect on Change Supportive Behavior in employees of the Coordinating Ministry for Political and Security Affairs of the Republic of Indonesia · (t = 4.403 > 1.97; p = 0.000), indicating that employee compatibility with the agency encourages active support for change. This support is reflected through participation in meetings, presentation of problems or input to leaders, and discussions between colleagues to equalize perceptions in completing work (Franco & Neiva, 2023; Mehboob, 2023). Thus, employee involvement that is in harmony with the characteristics of the agency accelerates adaptation to change and supports adaptive organizational performance.

The Role of Career Adaptability in Mediating the Influence of Person Rganization Fit on Change Supportive Behavior.

Career Adaptability did not mediate the influence of Person-Organization Fit on Change Supportive Behaviour (t = 1.252 < 1.97; p = 0.211), suggesting that career adaptation is an individual’s choice to shape work experience, but is not directly related to support for organizational change. Person-Organization Fit still encourages Career Adaptability, but Career Adaptability does not affect Change Supportive Behavior, which is prioritized from the perspective of organizational interests to organize the performance and new tasks of employees. Previous research confirms that challenging and varied tasks can increase employees’ ability to adapt and gain appreciation, so Change Supportive Behaviour is an institutional effort to adjust employees to their new functions and tasks (Liu et al., 2023).
