The Independants in our local do very well. Which we are located in Texas. Now they have a NON union shop around here called RICO and after they go in and destroy the unit we charge extra to fix it. You cannot beat a mechanic who went through NEIEP and had 4 year apprenticeship. Electricans and crane mechanics make horrible elevator men, which most of the NON union shops use. Ill find safety circuits jumped out, interlocks jumped out, door restritors not working. But I guess this terrible work practices can be used by anyone. But the difference is a man with a card in his pocket knows better.
A good lawyer will be your best asset. I wonder how much insurance you have to hold. But good luck
