1) The elimination of unpaid overtime for anyone that isn't a 'corporate office able to hire employees at will'.
2) Required 'typical hours' in employment contracts; companies can't pay out less than this unless the employee agrees, and the employee cannot be forced to work MORE unless they agree.
3) All firings have to be for cause.
I don’t owe you a job. If I don’t need you any more, why the hell should I be forced to owe you?
Are you required to buy the same amount of groceries each week? Why not? Same for labor. When you need less, you buy less, when you need more, you buy more.
Also, from the perspective of an employer, a valid reason very well could be the end of the project that a contract is for; such a termination / re-evaluation date should be built in to the contact and clear up front.
On paper the typical hours will be in the contract, but in practice only those willing to agree to less pay/more hours will be hired/kept, making it less of an agreement and more of an obligation.
