Have had several PT Sups. tell me they have the right to tell us to stack boxes on the belt 2-4 at a time and work faster each time they come in a truck in the Unload. I work PT Unload. Some say they can't because it is employee harrassment. In the contract it states that Managment may only direct employees, but not critique performance. Question being: Can managment really dictate how many boxes are coming out of our trucks and how fast?
