This provision doesn't prohibit overtime pay, it excludes that group of people from government-mandated overtime pay. A company could still choose to pay it's workers overtime, or workers could demand/negotiate that.
Unions are protected with various laws...then court cases pops up where there is some debate about if a Union can legally strike or even negotiate.
In my mind it is very clear. Do the workers have leverage? If so, then "the company??" has to negotiate...just like they would with any business partner.
In the end the courts are used as a bulwark against worker rights. Any victories for workers just give substance to the idea of governments intervening in business negotiations when board rooms want to socialize expenses.
Absolutely labor bashing.
