If you’re interested in forming a union, but unsure of what to expect, you’re not alone. Under the current American system for union recognition, unionizing is an arduous process and comes with some real challenges. It takes extensive organization among coworkers and differs for those in the private vs. the public sector. For those who work in the private sector, the National Labor Relations Board (NLRB) oversees the process of certification. It often — but not always — involves an NLRB-supervised election, where workers vote over whether they want to be represented by a particular union. Having some foundational knowledge around why unions form, what they do, and how they’re structured can help inform how you navigate this process.
