In my early 20’s (like 21-22) I worked in a work environment that is notoriously big for everyone giving each other shit at work (trades and labouring).

One thing I picked up on very fast was that you had to set those limits on how much crap you can take as a joke. It also made it really easy to know when an actual fight was about to break out because both parties would step over those lines immediately haha.

Anyway, I’ve done this at every job since and personally I’ve never had an issue with workplace bullying or anything. I swear the workplace is just the schoolyard for adults lol
