That sounds like a really tough situation. When a boss feels threatened, it can create a difficult and uncomfortable work environment. Here are a few strategies you might consider to handle the situation:

1. Focus on open communication: Sometimes, a boss feels threatened because they don’t fully understand your strengths or how your work benefits the team. It could be helpful to ask for feedback in a way that shows you’re open to improving, such as, “I want to make sure I’m meeting your expectations. Could you point out areas where you think I can improve?” This can open the door for constructive conversations.
2. Stay calm and professional: It’s easy to get defensive when you’re being criticized, especially if it’s unwarranted or feels personal. But responding calmly and with professionalism can defuse tension and show maturity. When possible, try to separate your personal feelings from your work performance.
3. Document your work: Keeping a record of your accomplishments and feedback you’ve received (positive or negative) can help you protect yourself. If the criticism becomes unreasonable, having a track record can support your case when speaking with HR or a higher-up.
4. Seek mentorship or advice: If you have trusted colleagues or mentors, talking with them can help you gain perspective and advice. Sometimes a third-party view can highlight areas for growth or help you strategize how to handle the situation.
5. Set boundaries if necessary: If the criticism turns into something more personal or crosses professional boundaries, you might need to set limits. It’s important to maintain your self-respect, so if the behavior becomes too damaging, consider addressing it directly, or, if needed, escalate the matter.
