Labor laws regarding working for salary?

my hubby works 48-60 hrs a week and is on salary.. someone told us that he can only be on salary if he is a supervisor (which he isn't.) on his paystub he gets each week it says he works 40 hrs even tho he works much more. when he goes to his boss , he says that if they just paid him for his hours and overtime , the company would go broke.. my hubby has been at this job for 6 yrs and has a love/hate relationship with them.. he make semi good money (around 50,000 yr) and GREAT benefits. is it against the law what they are doing? this is a big company with big contracts (million$$ contracts) Does anyone know if is is true that only supervisors can get salary? if it is true what can we do about it?

they never told him about not getting paid overtime... he does all the supervisors jobs just doesn't get paid for it..

Not just supervisors are paid salary, although that is typically how it's done.
If you husband agreed to be a salaried employee then he does not get any OT time.
At the same time though he should be able to work a 30 hour week and still get paid 40.

not true at all---- you do not have to be a supervisor to get a salary and it is probably against his contract not to get paid overtime. I would tell him to force his company to pay him for the overtime he works or he should go somewhere else. Typically a company makes only supervisors and higher salary because they tend to stay the longest.

Hmm, It might depend on where you live, here in texas you dont have to be a supervisor to be salary, and salaried employees are usually paid more than their hourly counterparts with the expectation that they are there working when need be.
