Could this be a protected concerted activity? In the US, there are some basic protections when two or more employees work together to improve the conditions of their employment. I don't know what does or doesn't qualify for this protection, though.

And there are probably not clearly defined rules for this. What would need to happen now is for them to file a complaint with the National Labor Relations Board and that group could make a ruling about whether this is protected activity or not.

Ayup. And if they're smart, they hire a lawyer for that.
