I just saw it happen again. Once the new project in town stuck a shovel in the ground, here comes the politicians and the unions pushing to break the promises they just made.
It seems to happen on every project. Once the deal is done, and it looks like the candidate is actually committed to the site, the shakedown starts.
Politicians who recently bragged about open shop conditions drag their union friends in to pressure the company to build and operate union only. Politicians pressure the company to use only local contractors, despite their smiles and handshakes committing to using the best available during negotiations.
But the most insidious of all is the permit shakedown. I worked on a project in recent years in a blighted area. I'll swear, all the local government administration did was sit around an create new permits with expensive fees.
You may think there is no way this kind of activity gets around, but it does--from industry to industry and contractor to contractor. If your local officials behave this way, tell them to stop it. You'll never know if this is the reason that new (auto plant) (steel mill) (paper mill) was built two counties over. They will never tell you.
