<p>The supportive role of the supervisor is inevitable to minimize the stress outcomes and promote positive behaviors in the workplace, especially in high-pressure work environments. Therefore, extant research aims to understand how work support (i.e., support from the supervisor) in response to critical working conditions interacts with individuals’ traits (i.e., future focus) to influence employees’ job-related psychological ownership and helping behaviors. The study utilized a time-lagged approach to collect data from nurses working in the healthcare sector in Pakistan. In total, 430 questionnaires were distributed, and 365 questionnaires were received. The data were analyzed in SPSS v22.0 and AMOS v22.0 to test the hypothesized relationship with a final sample of 349 responses. The findings suggest that supervisor support during critical situations is linked to spurring helping behaviors, and the relationship between supervisor support and helping behaviors is mediated by job-based psychological ownership. Moreover, the findings reveal that employee’s future focus moderates the relationship between supervisory support and job-related psychological ownership, with these relationships being more positive for those with a high future focus. The study showcases the practical evidence of social exchange theory by exploring the dynamics of supervisory support, which stimulates psychological ownership and motivates employees to help others balance the exchange relationships. This investigation demarcates the widespread implications to supervisors as to how they may demonstrate concerns through practical support activities and how staff can work actively by helping others.</p>
