In a FREE economy (i.e. "capitalist"), elements of market forces (i.e. labor) are allowed to band together into "consortiums" to NEGOTIATE contracts governing how much compensation is owed for services rendered.

If you oppose the existence of worker unions, but are suspiciously content with the formation of corporate collective bargaining organizations (i.e. Regional Airline Association), you either don't know what you're talking about...or you're some kind of authoritarian monster.

That's all there is to it.
