Well firstly, bodies corporate are obviously legal persons and nobody with any clue disagrees with that. But that isn't what I am talking about.
Every company has a board of directors who are natural persons, and ownership eventually is traceable back to natural persons, and their officers are natural persons. Grouping people up doesn't make them unpersons.
Worker and employer not your preferred languahe? Call it worker and manager, worker and executive, worker and CEO. Whatever you want. But the sentiment is very real. It is about treating the workplace as an antagonistic, conflict-driven, zero-sum environment. If I win, you lose. If you win, I lose.
I don't think that is how real workplaces actually work. I like my employer and I like my boss. Without them, I'd be out if a job. Without me, they'd be out of a worker. I don't think we have opposing interests at all.
It is definitely identity politics. It is the original identity politics: Marxism. The proletariat against the bourgeoisie and all that rubbish.
