So one of my coworkers is annoying, but I've let it slide since everyone else seems to like him. He has never finished a zone and whenever I zone with him I have to go through every single one of his aisles. He shows up late constantly and tries to top everyone's stories in the break room, even if he's not part of the conversation. While that makes me mad I would not go to an etl or hr over that. However there was a facebook post of a chat he had with a coworker, "Yo. Dude, get this: alli bailed on me on Sunday, I was so pissed.... I KNEW it was a bad idea expecting more from a black chick.." The team member he is talking about has never missed a shift, never called in, in the rare occasions she is late she is only late by 5-10 minutes, she picks up so many people's shifts, and is a close friend. If his joke was meant to be funny it was in poor taste and I'd rather not work with someone like that. What actions should I take?
