Things have been boiling up for a while at work (Ralph’s grocery store) and the two head managers at the store are absolutely slimy, rude jerks. Today I told them a shopping cart had hit my car in the parking lot and he said in a super rude tone “Ok? What do you expect me to do about it? I have nothing to do with that”. So I called him a d*ck and walked away. Minutes later he pulls up next to me in the parking lot yelling at me with his windows down telling me “You threatened me in the store and now you’re going to see what happens.” I never threatened him, and if anything him doing that was way more of a threat than me calling him a dick. I am part of a union so I’ll contact them in the morning but I’m wondering what he can really do about this situation and how I should handle it.
