My question involves employment and labor law for the state of: Colorado
I am considering going to work for a company that moves freight as well as hauling bulk fuel and they claim that they don't have to pay overtime since one of their divisions hauls fuel. These divisions go by different names and as far as I know they only haul the fuel and are not "bulk Distributors". I would be working for the freight division and as far as I know the drivers for the freight side do not haul fuel. My question is can they legally not pay overtime to the freight company employees based on the fuel hauling business?
Any information will be helpful.
