why do you need a union? everyone should just set their personal standards for what they accept/demand, and then let the market sort it out? someone wants to work for $20/hour programming, in a fashion that can satisfy some demand? great, then I will simply NOT be doing that job. Everyone wins even though I do not get that particular job. Someone is willing to work 7 days a week as they prefer to grind to earn more money? good on them. Its not gonna be me, They win the job, I dont.
Nobody wants to inhale toxic fumes in some factory? well then the company had better invest in safety equipment, or work dont get done. We dont need a union for this
