Protected concerted activity is the legal term, and broadly encompasses protections for workers who collectively discuss and attempt to improve, among other things, the conditions in their workplace.

I'm not redefining anything, the courts have broadly held that workers, when acting as a group and not just airing individual grievances, have protections for their speech. Things like corporate values, retention, recruiting, public sentiment, workplace diversity, etc are all potentially workplace conditions.

Workplace Conditions has a legal definition, but it is interpreted by the courts and those courts have the ability to adjust those definitions or interpret them as appropriate.
