One thing you find which I think makes it more competitive in my industry, being open shop, is that there are no delineations, if you will.
To give you a very easy example, I was an IBEW member for 15 years. Then I became an open-shop contractor. On projects that my people work on, we cross lines. We have the ability to cut a piece of plywood. We don't have to go to a licensed carpenter on a construction site because we're an open-shop facility. I also then don't have to get a painter to paint that piece of plywood with fire-retardant paint. My people can actually do that, and then we can mount that plywood and mount our equipment on it.
The problem with a lot of closed tendering is that you have these actual lines that do not allow one union to cross into another union's work, and into another. So a lot of times you have people basically wasting a lot of their effort.
