A service company has employees work standard shifts from 9:00 until 6:00. Once their shift ends, they are on call for emergencies. If they are called out during on-call time they get paid a minimum of four hours.
Can an employer schedule jobs right up to the end of the scheduled workday in order to avoid paying the on-call wages, even though that extends the employee's shifts into the on-call period? For example, could a task that will take an hour to complete be scheduled at 5:50, or even 5:59?
