28 Powerful Things You Should Never, Ever Say to Your Boss

“I’m So Hungover”

Why It’s a Problem: Announcing that you’re hungover is unprofessional and gives a poor impression of your dedication to your job. It signals that your personal life is interfering with your work responsibilities.

Better Approach: If you’re feeling unwell, simply state that you’re not feeling your best and focus on maintaining your professionalism. “I’m not feeling well today, but I’m doing my best to stay on top of things.”
