The contract you mention can not go into such detail, avoiding any appearance of command control. Or does it?You signed the contract. Was there anything in it that said fedex couldn't make you deliver more packages in the same area??????????
Well X ultimately can not make any of us do anything, that's the ultimate problem with contracting this sevice out.
The recourse,,,lose the contract, but if all of us weren't so ECONOMICALLY DEPENDENT on X it wouldn't effect us much losing a contract now would it.
