But IANAL firing some one for telling their co-workers about their right to unionize is an illegal reason to fire someone. I'm not completely convinced that's what happened here but still

Technology makes a lot of these good intentioned laws hard to interpret. You cannot be fired for telling your co-workers that they are allowed to unionize. What if you work for a call center, commandeered an auto-dialer, and called every co-worker in the company with the same message? What about a popup on every page of an internal company website? Is someone allowed to stand up in the middle of the office with a megaphone and tell everyone they can unionize?

The law already covers situations like this, in terms of whether or not employees are allowed to use the internal technology tools of their employers in order to organize.

So what does the law say?

Organizing is protected by law. Firing for organizing is intimidation.

Yep, that's what's contested here and is unclear.

Is using whatever mechanism is available to you, including company privileges, in order to organize perfected by law? As a customer support person, would you be able to add "you have the right to sue Google," simply because they did have the right, and I felt like it? Am I allowed to write a script that helps draft automated verbiage to assist you in suing Google?

Right, but retaliation for engaging in a concerted labor effort is specifically an illegal reason to fire someone.
