When I was at my new job for about a month, the light bulb in a cheap plastic fixture went out. This is the type of fixture where you rotate the whole thing and it lifts out. It was mounted on the wall just inside my office door a bit over my head, but easily reachable. I asked if there were light bulbs in the supply closet, and was told the secretary would contact physical plant.
About a week later I came in and saw the plastic fixture lying on a chair and thought, good, they’ve changed the light bulb and forgot to put the fixture back. I tried the switch – no light. I told the secretary something must be wrong with the fixture. She said no physical plant would be back.
Three days later I came in and the light WORKED. The fixture was still on the chair. I let it lie there for another week not wanting to interfere with some union situation, but eventually after about another week put it back myself – the work of about five seconds.
This was 20 years ago. I expect the grievance is still working its way through channels.
