How do I deal with a toxic boss or coworker?

Dealing with toxic people at work requires strategy and self-protection. Document problematic interactions in writing with dates and details. Set clear Personal boundaries about what behavior you will and won't accept. Don't take their behavior personally - it reflects their issues, not your worth. Focus on your own work and avoid getting drawn into drama or gossip. Seek support from trusted colleagues, friends, or a therapist. If the behavior is severe or affecting your mental health, consider speaking with HR or your supervisor. Sometimes the best solution is finding a new job, but protect yourself in the meantime.
