I heard a center was shuttling low seniority drivers/peak driver to and from work from an off site park and ride, and that these drivers were being compansated or their time waiting for the shuttle that UPS had provided for them. Would seem to reason that if UPS is insrtucting you, an employee to perform a task then you should be compaensated. The security is acting as an agent for UPS, insrtucting you to perform a task?
