Is it a good idea to point out my coworker's toxic behavior ?
Why would you do that, did he hurt you personally?
No, I just think he's a jerk; that's enough of a reason.
If your coworker is behaving in a toxic way, you could try sitting down with him and talking to him about it. It would be best to talk rationally instead of calling him out in an angry way that will ruin your working relationship.
Nah, I'm going to talk to my manager and make a big deal about it.
If he's being that toxic it's alright if you wanna take it up to your manager. I hope you think that'd help.
