My Job Is Driving Me Nuts!! (In a bad way)

I swear, if it weren't because of College. I WOULD HAVE BURN IT THE MOMENT I SET FOOT ON IT!!!

Sorry for the outburst, for those who don't know. I work at a Frozen Yogurt and Ice Cream franchise, I don't mind working under pressure, but they really step over the line. Non-paid overtime workers, some Managers are assholes, etc. Want to know what happened? Read if you want:

It all started, yesterday Now you see, I went to work and began to do my usual routine, clean some stuff and help my friends since many have quit (Can't blame them) However I told my boss I had tests this week so if there was some chance that they weren't many clients he would let me study, he seemed ok at first. But then he forces all of us to do deep cleaning for no reason, to make things worse I had to clean 2 Freezer before we close, and those things are huge and hard to clean without help. Luckily I manage to finish before time, so yeah I was frustrated cause I had no time to study and had to recover much stuff today.

Now here's what drove me off, today I went to my boss and asked for a week of vacation since I've been working for a year after a new contract...he told me that I had to wait until December because that's what my new contract was signed...HOW THE FUCK IS THAT POSSIBLE WHEN I CLEARLY SHOWED HIM MY DAY ENTRY WAS ON JUNE?!?!?! (I had the document, but he said it doesn't count) and to finish the salt on the wound...another deep clean of the place and to put some lime on the wound...ANOTHER FREAKING FREEZER!!! (Luckily it was only the top part and will not clean it until Sunday)

So yeah, after my Tests I'm going to look for another job. So wish me luck and thanks for reading ^^
