^ That was how I was imagining it. Am I wrong in thinking this way? Or is the argument that the urge to specialize is independent of wage?
Let's look at ATC as an example:

> Their work can be stressful because maximum concentration is required at all times. Night, weekend, and rotating shifts are common.
Well, maybe there could be better agreements than rotating shifts on a very stressful job, don't you think so?
Generally, the more specialized labor is, the higher wage and benefits they can demand in a capitalist labor market. Supply and demand. For less skilled labor like general electricians I can understand the role of the union in negotiating for wages, benefits, and safety standards. For highly skilled labor like an HVAC tech, I don't see it.
