The whole "work wife"/"work husband" thing might be fun to some people. But to others, it's just inappropriate.
One man is wondering whether he did the right thing by kicking his co-worker out of his wife's baby shower for going on and on about her self-proclaimed "work wife" status. He took to Reddit to ask if he was the a-hole for taking such drastic action.
I (29m) work in a pretty tight workspace. We have about 9 of us in my department and it's a pretty even split between men and women. There's one coworker "Eva"(20f) who started working here a few months back. She's really good at her job and seems to get along with everyone. We get along well as we work on projects together and are usually in the group of people that are the last to leave most days.
