We used a union shop for electrical work at a mall renovation because they were the lowest bidder. They did a decent job at first, but they were slow. We kept asking them for more manpower and the same three guys would show up (one would work, one would supervise, and the other would train....they needed at least triple the productivity to keep up). At one point they were 5-7 weeks behind. They started leaving equipment behind and not picking up after themselves. It got really bad when the finishing crew would have to work around their slow pace.
I had two slashed tires the day after I made a change order go to a non union shop. Inspectors stopped showing up after that too, so we ended up delayed even more.
I had to hire the union crew back just to pass an inspection or even get the inspector to show up.
