Team members can request and provide backup from one to other members, which can help teams with high workload achieve dynamic workload optimization at the group level. However, studies on this issue are limited, especially on real‐world high‐risk operations. This study explored how to approach air traffic controllers make backup decisions in the dependent parallel approach operation. In this study, we focused on how individual difference factors can influence the controller's backup willingness and decision. Forty licensed controllers performed 32 simulated scenarios varied in their own task load, the backup recipients' task load, and shorter taxing possibility. We also measured their job satisfaction and work experience. Multilevel regression analyses showed that controllers with a higher level of job satisfaction were more likely to provide help to their colleagues. Moreover, when their job satisfaction was high, they were less sensitive to the seemingly inappropriate request, but they only used their additional resources to help others. The findings were discussed in the literature of teamwork and aviation safety.
