I was present when a facilities manager explained why we shouldn't use spray-cleaner to clean whiteboards, because it wore down the paint faster, and repainting it cost $10k, and that they had already paid to repaint them twice.
...and then the facilities manager threw up their hands, sighed, said "yeah, but what can you do..." flipped through a couple of emails on the old smart phone, then went and sat down and watched some crap on youtube for a few more hours, until oh... 4:35 PM, close enough, and clocked out for the day, with the wall still unpainted. C'est la vie.
My understanding is that per regulations only union labor is permitted to perform various tasks -- you can't just call any old contractor to install light fixtures.
This was a requirement having to do with the location, I am not sure about the specifics (if it was a city thing or if the building owner had entered into such an agreement) but I'd like to have a better understanding. On the face of it, it does seem absurd.
