- Person A is a little more senior in an organization than Person B, and Person A delegates some work to Person B.
- Over time, there is some dispute over how well Person B is doing their job.
- Person A asks Person B to resign.
- Person B stays, and keeps getting paid, because they know Person A can't fire them.
- Person B tweets out "I've been fired, donate here."
Is "Person A fired Person B" at all a fair characterization of that situation? I don't see any way someone who claims they were fired and asks for money while still drawing a paycheck is in the right -- they're just straight-up lying.
There's room to criticize Robinson for not handling a difficult situation particularly well (and for not setting up a better group structure in the first place), but this is wildly different than "he fired employees for unionizing." There's was certainly no effort to unionize, in any case.
