Sure, but the problem is that the UAW is likely wrong. Their work, relative to its substitutes is of lower value to the company on the margin. It is also why the NBA doesn't compensate, say the concessions workers millions, they can more easily be replaced. Likewise, the team's medical staff is payed much better both due to the alternatives they could find outside of the sport, and due to the relative difficulty in finding talent.
The UAW has skilled workers, and they are compensated well in general. Perhaps they should earn, more or less, I'm not sure. But the relative value is exactly the point.
The NBA compensates workers based on the value they bring to the team. Isn't that what the UAW is arguing for?
