It’s not in an employment-at-will state. You can be fired at any time for any reason as long as it can’t be prooven to be because of discrimination against a federally protected status, or some bullshit wording like that.
It most definitely is illegal in at will states. The prohibition falls under ‘retaliation’ which covers everything from being fired for refusing to go on a date with your boss, to being fired for wanting to unionize.
It’s very explicitly illegal in the US at the federal level (and therefore in all 50 states) to fire someone for ANYTHING related to an attempt to join or start a union. Seriously. It’s also illegal to explicitly tell your employees not to unionize, and to even threaten retaliation. Which means every single employee of that company should be talking to that lawyer right now to sue their boss for every last penny he owns. Or at least get him super-mega-awful fined.
You know, it’s not often that you see every labor law lawyer in the tri-state area reach climax spontaneously and simultaneously, but damn here we are.
