Slightly off topic, but could someone explain why employees in the US keep having to form their own union at each company, rather than the employees just joining an existing union? If I wanted to join a union where live, I'd just pick a relevant union, go to their home page, and click 'join'.
In most other countries, before that point workers can still be union members “at large” get support from members in other workplaces and from the central union in their quest to gain recognition in their workplace.
