Proactive behaviors matter for my job! The roles of career decidedness and career stress in face of VUCA

Purpose Drawing on the conservation of resources theory, this study examines how proactive skill development (PSD) influences job performance and mediating and moderating mechanisms underlying the above relationship. Design/methodology/approach Data were collected from a sample of 261 full-time workers in three waves, spaced by a six-week interval (Time 1, N  = 360; Time 2, N  = 320; Time 3, N  = 261). Findings The results confirmed that career stress mediated the relationship between PSD and job performance. Additionally, high career decidedness strengthened this negative relationship between stress and performance. Furthermore, career decidedness significantly moderated the indirect PSD–performance relationship via career stress, accentuating the indirect effect when decidedness is higher. Originality/value This study sheds light on the important role of proactive skills development in influencing job performance and what factors can affect this relationship. It offers practical implications by highlighting how targeted training can boost employees' proactivity and performance.
