The basic problem here is that these people do not have so much as a basic grasp of economic law.
A business cannot pay its laborers more money than they bring in to the company or the business ends up like the US automakers - Overpriced, overstaffed and run by the employees for the employees and the end user be damned.
If the market value of a job is $8 an hour a business cannot pay $15 an hour for that service and remain profitable and compettitive.
But if these complainers were smart enough to figure that out they would be smart enough to qualify for better jobs.

The UAW contracts are structured as promises to manufacture a certain amount of vehicles that will sustain the payroll during the contract.
Note, there is little or no thought as to how many of those vehicles are actually sold during the contract.
