With a fundamental shift in the way people build their careers, a growing number of working individuals are moving to gig work to build their careers. Such changes in the nature of the career landscape pose significant implications for career research to develop new knowledge. Career success is one of the essential topics in careers research to assess and understand the primary objectives of one’s career actions. However, the measures of career success also depend on the context and type of chosen career pattern. In the current study, we adopt a qualitative approach to conduct 19 semi-structured interviews of gig workers to unfold the indicators of gig career success. Further, we highlight several individual proactive behaviors that gig workers engage in to achieve gig career success. We further discuss the implications of these findings to the careers literature and practice.
