My answer is: Unsuccessfully. A different, more useful question is: How should you deal with toxic co-workers? It depends. Here's a guideline: 1. If you can, talk with the coworker about what's making them toxic. 2. If that doesn't work, or if you can't talk with them, then talk with HR or the lowest-level boss that you have in common. 3. If that doesn't work, then do what you can to not work with that person. Good luck.
