Work related problems!

Ok im just venting here…

I got a new job washing dishes two weeks ago.
My first day i worked 11 and a half hours.
My second day i worked 6 hours.

Now he has me working all weekend.

5-12am

I called him to tell him that i was not going to be able to work tonight because i have plans.

He told me that tonight is going to be busy and that i had to work.

I said that i blew off my friends to work last night.

He told me that he would like to hang out with friends but he cant.

He said that i should hang out with them on thrusdays.

Im only 16, i shouldnt devote my entire weekend to work.
I need to spend time with my friends, and be a normal teen.

What should i do about this?
Im thinking about quitting.
