How to Stay Calm at Work When a Coworker Acts Like the Boss

Dealing with a coworker who constantly oversteps their role can be frustrating, but staying calm and composed is key to maintaining professionalism. Start by setting clear boundaries—acknowledge their input politely but assert your own autonomy. If they attempt to delegate tasks or give orders, respond with confidence by confirming expectations with your actual supervisor. Practicing deep breathing, mindfulness, or stepping away for a short break can also help manage stress in the moment. Keeping your focus on your own responsibilities rather than their behavior ensures you remain productive and unbothered.

If their behavior becomes too much, a direct but professional conversation can help. Approach them in a calm moment and say something like, “I’ve noticed you like to take charge, but I prefer to handle my work my way. If I ever need input, I’ll definitely ask.” This keeps it respectful while making it clear that you’re not feeling their approach. If they continue, reinforce your boundaries with a firm but neutral response like, “I’ve got it covered, thanks.” If the problem escalates, bringing it up with a manager as a concern about teamwork, rather than a personal issue, can be an effective way to resolve the tension without unnecessary conflict.
