dMaybe in Alaska but in California construction unions are a thing of the past.
By 92 I was forced to close down a 56 year old construction company by the competition that I speak of.
The only companies still using union labor are the few survivors that are doing work on large projects where the owners are signatory such as GM where one non union worker gets the entire plant closed, had it happen at GM Van Nuys when a fired steel worker bitched to a steward that the steel company had non union help, which it didn't, but the GM plant was closed for 2 days while it was sorted out.
At this point, my estimate is that over 90% of the construction comoanies are using illegals and paying cash.
True, Alaska is a union state. The new TransAlaska Natural Gas Pipeline, $20 billion, will be built with union labor. Even so, a number of employees show up with bogus experience claims, which if they don't screw up may go undetected.
We had a flood at our house last year, insurance paid for the rehab. The company our insurance contacted called me to make an appointment to start. I told them if you use illegals don't bother, I will find someone else. The lady at the construction company told me they do not use illegals. The reason is that when they do insurance rehabs people are usually still in their homes. They can't/won't take on the responsibility of using illegals in a situation like that.
Apparently companies working for insurance companies are the ONLY ones not using illegals here in Calif.
