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.
