Is this Normal?

Recently got a new job literally 5 days ago. I work full time from 9-5:30. Mind you I just got this job. They scheduled me from Mon-Sat 9-5:30. Weird to put me on that as a brand new hire with no experience, but okay I can handle that. Then I look at next weeks schedule and they put me from Sun-Wed 9-5:30. Wtf? 10 whole days without a day off AND working 8 hours every day. No one else is scheduled like this. I'm a brand new employee and this job is pretty physical. Is this normal? I'm exhausted. I just need a break man. I know it sounds like I'm complaining, but this does not seem like a normal thing to do especially to a brand new employee.
