I need to rant about work!

Okay so I work at a restaurant. Basically been working here for 4 years! I'm not normally a person to call out but I finally needed a couple of days to finally relax. I work 6 days a week and I work a lot of doubles meaning pretty much 12 hour shifts.

Well I was off sunday, called in Monday and tried again today cause I'm fucking tired! I told them i was sick honestly so i could just stay home with my daughter (i know it's awful but i dont see her much right now). Well my manager messages me and says no one can come in tonight and that she needs me to come in....now I was alittle upset about it but I did it anyways.

As soon as I stepped into the kitchen, my boss, asked why I was there. I looked at him like he was crazy (btw I told him in the morning I was sick so he knew). He already asked the cashier that morning if she could take my shift and she said yes.

So I straight up told him that the manager told me to come in and that's what I did. Now everyone here thinks I'm pukey sick just saying. She then tells me she didnt know until she told here. She had time to tell me cause she came in at 3:30 and I came in at 4. She then asked me help her take this tray of food to her table. I was more pissy that she asked to help her after I already told her I'm sick. Maybe I'm in the wrong and I'm crazy but it pissed me off enough to say fuck it I'm finding a new job.
