How do you get boss investigated when they are the problem at work?

To address a problematic boss, start by documenting specific incidents that demonstrate their behavior and its impact on the team or workplace. Gather evidence, such as emails or witness accounts, and consult your employee handbook for procedures on reporting grievances. Consider speaking to HR or a higher-level manager, presenting your concerns professionally and factually. If possible, seek support from colleagues who may share similar experiences to strengthen your case.
