Work rant. Yet again.

I was scheduled today 8:45am-1:00pm. Which is fine because I know how to open and do all that. So that's not a problem. What is my problem? The manager who was my relief was an hour and half late for work, then proceeded to cry to our big boss that she "doesn't feel good" and "wants to go home". So what does my boss do? Calls me back in to work. So I was home from 2:30-4:30 and had to go back into work because this girl was upset about her BOYFRIEND LEAVING HER. top it all off. We close at 7:00 on Sunday's; well she didn't do a single thing that she was asked to do while she was there. Because she just sat in the office and did nothing. Seriously. I went back at 4:30 and did ALL of her work and then work that's suppose to be done tomorrow.. I'm so mad. Now my back hurts, my feet are swollen. Seriously 5 weeks till my maternity leave. I cannot wait. 😭😭😭😭
