It was only 50 years ago that the Republicans were the party of labor unions [4]. How times changed.

Also, be very careful in comparing unions in Europe with the US, the systems are very different. Unions in Norway for example are not "per company", they are usually working across a whole industry or even across all industries for a particular education/work-role (like engineers). Employees chose freely whether to be member of a union, or which one to pick - and membership is independent of an employeer/contract.

The UAW theoretically got involved in the employment contract negotiations, but none of the RAs could get in touch with them despite paying union dues. There was a group trying to organize action to leave the UAW and form an independent union.
Large organizations tend towards incompetence and corruption over a prolonged period of time.
There are other easier ways to address that differential. Namely: unionization. In many European countries, there are no minimum wage laws. There is no government agency equivalent of OSHA. Instead, they have unions, where workers themselves band together and collectively bargain to ensure they're adequately compensated and given a safe working environment.
Instead, we in the United States, have chosen to make the government our union. Then we're shocked and surprised when it does a bad job, or when its blanket policies have disproportionate impact on certain industries.
