They will overwork you if you give them the chance. It is not uncommon that they have people working 6 or more days straight. That being said, you won't get any over time, they structure your hours so you could work 8 days straight, and not receive any over time.
They are willing to cross train people in different departments. That being said if you have received a raise or 2 in one department, when you start working in a different department, your raises are void and you will start at the starting wage of the position you are working in. So if you are working $16 as a houseman, if you are getting cross trained as a bellman, your wage when working a bellman shift will be $14.50. They also don't mention that to you unless you bring it up.
There are many more problems with this company and the way they treat their employees.
Overworked, little room for advancement, will screw you over if possible
