Screwin' with my pay, lookin' at a long hard day serving ice cream

Yea, it finally happened. After working in all the different outlets  my pay rate for some of the time worked changed. From $15. to $8.60 an hour...yeesh. I went to my immediate supervisor, he put the blame on his boss, who happened to be gone for the next week...hmmm. It was my training that managers are to act quickly correcting pay problems. And this morning, at 7am, when I had just gotten back from a run,  I was asked to go into the snack bar early and be expected to work alone all day....two of us working yesterday sold $1200.00 worth of soft serv.....lol, and this after seeing my messed up paycheck yesterday....I'm going to persevere, and see how it goes.
