More to add to my story, we have a method of reporting people who have bad behavior, it’s called Peer Feedback, it can be good, or it can be bad. I got a Peer Feedback from this guy, my manager forwarded it to my Inbox and just said what he had to, that I should not use “meh” as much, then in person he said that guy needs to not take the word “meh” so seriously.
