I support unions. If I ever have the chance to organize one with future coworkers, I’ll do it. And I will always vote in favour of unionization, as well as actions beyond that, like strike action. We don't have enough unions or strikes in Canada. Strikes work, especially when the union or unions doing it is strong. Simply put, unions give you the right to fight collectively. A union is you and your coworkers banding together for better conditions and pay at work. In a union, you become stronger than the employer, who will pay you as little as possible to make as much money as they can off of your work.
This section used to be about how employers attack workers trying to form a union. There was too much to cover, and I'm not proficient enough to write a concise summary. Luckily, the linked article above by Amary Wiggin explains what to expect from an employer if you try to unionize.
Of course, it's easy to write "I support unions" or even "innoculate yourself". I've (unknowingly) attempted to organize a union once, but once was enough to learn that unions are one of the best and most accessible ways to improve the lives of workers. After all, the workplace is where most of us are - us being people who have to work for a living. We give the best hours of the best days of the best years of our lives to employers, as economist Richard Wolff has said. It's worth improving your own situation, and the best way to achieve that is to form a union.
Mass unionization can help us win permanent universal benefits, like making paid breaks into law. Long ago, unions won us the 9-5; the 8-hour workday. For generations, it was an unspoken rule that you would get a lunch break while on the clock. Then, employers slowly stole another half hour of the day from us, because they insisted on the letter of the law. (Much of labour law was written to protect employers and the wealthy, at the expense of worker protections against employers.) A former employer once took away the tacit paid breaks from my former coworkers and me. 8-hour workdays became 8.5-hour workdays for those of us who dared to eat at work, just to not starve. That single act of utter tyranny, callousness, and inhumanity taught me everything I needed to know about whose side I want to be on in what is and always has been a class war.

Unions: A Revolutionary Critique - Of particular interest here is the quote from Red and Black Notes. The rest of the piece elaborates on why unions actually have a mollifying, weakening effect on frustrated workers. In effect, unions actually prevent more strikes and maintain productivity / normal functioning of a business.
