When facing a manager who may be holding back your career, it's essential to expand your network to include higher-status individuals within your organization. Actively seek connections with other managers and those in adjacent functions to gauge the social capital of your current manager. Understanding their influence on promotion decisions is critical. During performance reviews or interviews, ask about the promotion process and the importance of a manager's social standing in advancement opportunities. This proactive approach helps you identify potential barriers early on, allowing you to navigate your career progress more effectively.
