Here is a good example how the union works. I lived in post housing and the oven broke. To get this replaced the following had to happen. The guys who moved stoves came in and moved it away from the wall and then we had to wait for the electrician to come and unplug the stove so the stove movers could move the stove out. Then the stove movers had to bring another stove and then wait for an electrician to plug it in prior to moving it into its final resting place. I told the stove mover guys that I would unplug and then plug the stove in and you would have thought I had suggested anarchy..
