Boss got on my ass for not coming in today. Texted him last night saying I won’t be coming in because I have to take care of my post-op mother since there’s no one else home. He said he doesn’t like how I manage priorities and has been rude ever since. Am I in the wrong ? Check body for context.

I’m a student and this is my part time job at a local grocery store. I’ve been here for a month and a half. Never called in sick, always was on time and did my job. I texted him the day before at around 6PM, turns out he “doesn’t respond to messages” when he’s not at work, understandable.

Key point about this situation: we’re critically understaffed, me and my boss are the only employees for our department. He can call someone in to replace one of us but hates when he has to replace me since I can just “be there” and because it costs him money (?).

He started yelling at me in front of everyone else, saying that I don’t even have the decency to text him the day of my shift and that my sense of priority is messed up.

Did I do something wrong or are his expectations just unrealistic?
