Alright now, I am starting to get tired of people who
still think that millennials are effectively children. I am a millennial. My 36th birthday was last week and I've been diagnosed with degenerating discs in my back and my hair is turning grey. If those aren't signs of age, nothing is. The oldest millennials are literally turning
40 this year and even the youngest will be 25
according to Pew Research.
On to the topic at hand though, the point of a union is to provide an organization with enough leverage to negotiate on equal terms with a corporation. As an individual employee, especially in an unskilled position, your leverage is effectively zero. If you want a raise to match inflation they could just let you go and find someone else willing to work at your current wage or less. However, with a union, if the union and the employer can't come to an agreement over wages or benefits then suddenly the employer has no employees, and even if they decide to call in new people to cover for the ones on strike, a factory or warehouse full of new employees won't be very efficient (not to mention the bad press).
None of this is to say that I don't understand the problems that unions can cause. They, like any organization made up of humans, can become corrupt over time. Look to police unions for examples of this. Unions that protect even horrible employees from firing or that squander their members' dues need reform but, that's best done by the members of those unions not by trying to destroy them outright.
