Should I report one of my coworkers for vaping inside?
Why would you snitch on your coworker?
I don't think a smelly coworker belongs in a work environment.
You should speak with the coworker first and let them know the smell bothers you. It's not nice to be a snitch.
I will tell on them. Never share your private info with these fuckers.
Why tell on them? You would be a lot more liked it you take this coworker off to the side and explain that they're going to be told on if they do not stop-- this way they'll respect you for giving them a chance, and they will most likely stop out of fear of losing their job. You win in every way doing this.
