Years ago the first building I worked out of barely had any heat at all. None in the area we worked in. Back then we had to change into UPS pants in the morning and couldn’t wear them home at night.
The dressing room had a small heater in it but the room was always super cold anyway. Our Steward put a thermometer in the room and filled a grievance. The center manager brought in a small space heater that did absolutely nothing unless you were standing right in front of it. He put the thermometer about six inches away
and assumed he had solved the problem. The Steward took a picture of the thermometer showing 110 degrees and filled another grievance. We got an actual oil burning furnace in the dressing room.
