This is going back about 12 years ago when I live in 'Joyzee'. I helped a friend, who is a computer technician, move a financial company from one of the World Trade Towers to the other. The job involved setting up, restarting and checking all of their PCs and it had to be done over one weekend.
Being in NY City everything was union. I was not allowed to pick up, plug in, attach or otherwise touch anything until the actual start up and testing of the PCs. I had to wait for a union laborer to move a PC, monitor, router and or printer from the cart they were on to a desk at a work station. Then I had to wait on a union electrician to hook up the various wires. Now mind you most of them were computer clueless so I would have to stand there and tell them what wire to plug in where. I was not allowed to even push the buttons in the freight elevator myself, they had a union guy for that.
My buddy's company payed me something like $45 an hour to point and say "Put that here.", "Plug that wire in there." and run a simple diagnostic test program. I can only imagine what the union boys were making.
