Try saying:
I’m committed to doing my job well, and I’m open to feedback and direction. I also work best when expectations are clear and communication is respectful. If there’s a concern with my performance, I’m happy to discuss the specific issue and how I can improve. I’d also appreciate having the opportunity to ask questions and share relevant information so we can find the best solution.
Remember:
Keep your tone calm.
Stick to the facts.
Document important conversations.
Don’t let someone else’s poor leadership change how you conduct yourself.
