What makes you think working for a living is servitude? It is a barter system that pays for work rendered in a commodity [coin of the realm, usually]. If you don't like what you're being paid and think you are worth more than what you are paid, calculate your individual worth to the company's bottom line to prove your individual worth. And one does not need a union rep to do that for them. All workers should figure out that formula and calculate it themselves, and say "heave-ho" to the unions of the world, which are as worthless as buggy whips. That's how personal wealth is developed.
Better yet, stop working for a job and be the job. Self-employment allows you to set your own wage for product/services rendered.
