>The current main unionization effort basically says "things will be better for everyone" on their FAQ. Total bullshit.
What is your familiarity with how a union works? An industry-wide unionization effort cannot effectively state what the future will hold.
When employees decide to try to organize a union within their company, they decide what the issues are. Their task is to convince their coworkers to join the union, so they will be focusing on the pain points unique to their own employment situation. Maybe in one company, it's crunch time, while in another, it's keeping a more consistent labor force despite project sizes changing wildly over time.
The new union will then negotiate a contract on behalf of its members. Each new union will be focusing on different things.
An industry-wide organizational effort that focuses on work hours and profit sharing would not catch the interest employees at a shop with good hours, good pay, but zero job protections and inadequate health coverage (for example).
