You see Tommy I used to be a local truck driver. I've seen dozens of companies pack up and leave. When possible, I spoke to the supervisors and in a few instances the owners of these companies. It killed them to go, but they had no choice. It was either move away from the union or join their employees in the unemployment line.
Unions were fine when they started out because they had no real strength. As time went on and they got stronger, their demands got higher. If you think they did so on behalf of the worker, you live in fantasy land. The more money the union gets their workers, the higher their union contributions. It's the unions that got greedy, not the companies.
With that strength came mutiny. Unions virtually took over companies. They told the company who they can hire, who they can fire, what the workers will get paid, and who gets the promotions when they come up even if they can't do the job. Nobody can successfully operate a company that way for any long period of time.
Like I said I could write a book on it, but one situation that comes to mind is I did my daily pickup at a company. The shipper was perturbed that I came there even though we were there every day. He apologized for his behavior, but went on to explain that every time a truck comes in, he has to stop packing parts and load or unload a truck.
I remember him telling me the company gave him help, so I asked what happened to him? He said he's still there, but totally worthless. The guy bid on the job of shipping and receiving and easily got it because of his tenure, but he was afraid to drive a tow motor. So I asked why he didn't tell his supervisor about it? He said the supervisor is helpless because of the union. So I asked why he didn't address the union of the problem. He turned off his tow motor, gave a great sigh and said "I can drive this tow motor right through the front of your trailer, but because of the union, I'll still have a job tomorrow. But if I ever told the union that a union man can't do his job, they will throw my ass out of here in two minutes flat." He started the tow motor up and finished loading me.
