I’m so tired

Every single weekend my boss is constantly trying to get me to cover someone else’s shift on my days off. There wouldn’t be an issue if I was rested, but I’m beyond fucking exhausted because I’ve picked up so many extra shifts this month. At this point I’m telling her no, because I just want my days off and not have to think about work. Im so tired of work...

Now she called me in for Sunday graveyard, but I have an oil change early Monday morning, and I was supposed to go see/hang out with my best friend I haven’t seen in a month BECAUSE of working so much.

I’ve covered maybe 4-5 shifts this month. Nope
