Also the company can benefit from it by no longer having to agree to accrued time which means if the setup had people bankng time they would be paid out on it when they retire, leave, or get fired. This allows them to save all that money each person had been saving. If the company is willing to set things up like this you should always be asking how do they benefit from this change.
