Is AUTHOR wrong in the post ? POST : Today is my day off and I live a solid half an hour away from the place that I work. A week ago I agreed to doing an 8am to 5pm shift on this Friday and next Friday, as well as coming in early on Monday to help out. It’s mostly because of the overtime pay since I’m a full time employee and I could use the extra money. I’ve been working at this place for a good three months now and haven’t had any issues with overtime. My manager isn’t the best at communicating things so I always have to sit down and talk to her, asking specific questions. “What time exactly do you need me to come in? What are the plans for that day? Did you do [insert task here] yet?” Etc. And sometimes still I’ll show up to a shift and have to do some of her work because she didn’t do it. I’m just adding this here so you know that she typically has me doing work that’s her responsibility to make sure it gets done, because she trusts me to get it done right. That’s one of the reasons why I haven’t had an issue being able to pick up overtime. 

Two days ago she let me know that her boss told her to try to find a part timer to do those shifts instead so they don’t need to be payed an overtime salary (time and a half pay). I told her I understood that, and I wanted her to let me know the moment she found someone, as well as to take me off the schedule once she did. Yesterday she told me about the girl she found, but she also told me that the girl could only do 9:30am to 4pm which wasn’t really going to help as much. She said she was going to call and talk to her. Again, I told her to please let me know if she didn’t need me to come on Friday. Fast forward to today, I show up at 8am for her to ask me “What’re you doing here  Big-Purple-Dinosaur?” 

Honestly at first I thought that it was a joke. I told her, “I’m here for the 8 to 5.” And she basically told me that she got the other person to do the shift even though it wasn’t the full shift just because they’re part time and her boss would be happy. But, that if I wanted to, since I was already there, I could help out by calling that person to let them know they weren’t needed today. Now I’m not the kind of person who’d be comfortable doing that. That’s something that’s fully her job, and it’s something that should have been done the day before. I told her it was fine and that I’d just go home to ‘sleep’ or get other things done. She said goodbye and closed the door on me so I left and took another half hour to drive home. 

On my drive home I couldn’t help but think about the gas I wasted, the fact that I woke up early and got everything ready for the day on my day off just to have to go back home. Once I got home home, I sent her the following text message:

“Hey, sorry about today. I know we talked about [part timer] coming in today. You told me she could only stay till 4 and that you were going to talk to her about things. I told you I could only stay till 5 and you said that was okay so I thought I was still coming in. I guess it was just miscommunication. Did you find someone to come in early on Monday? Is [part timer] going to do next Friday too? Just keep me posted. Wouldn’t want this to happen again.”

She’s read it and hasn’t responded yet. 

Am I an asshole for being upset over this and the way I talked to her? 

TL;DR Boss scheduled me on my day off for a shift. Gave the shift to someone else. Didn’t really tell me not to come in. Drove half an hour up a mountain to get to work just to drive another half hour back home. AITA for being annoyed and how I acted in response?
