(My job is in a small wardrobe room for a business and I do the closing shift alone most nights. I recently had a minor surgery on my left arm and was told not to lift anything heavy with it for a few days to allow the incision to heal. My supervisor was informed of this ahead of time and I remind him of it, as well, when I come into work for the day.)
Me: "I can do the regular work; I just can't lift any of the boxes or really heavy things for the next three days."
Supervisor: "Okay, we'll work around it."
(Five minutes later.)
Supervisor: "Oh, they decided they want to repaint the room after we close tonight. Since you're closing, I need you to move all the racks to the center of the room, and move all the things from the computer desks to the center table."
(This includes several desktop computers, printers, and heavy heat presses. I point at my bandaged up arm.)
Supervisor: "Can't you just lift them with one arm?"
