They talk about identity politics all the time. It is us vs them on everything. Worker vs employer is the quintessential example. Two groups that in the real world must work together, and do. But in the mind of the political left they are not just people that occasionally have adverse interests but mostly shared interests (my success is yours). No, they are sworn enemies.
I don't think you know what "identity politics" are, which is kinda funny to me. I would love to have discussions where identity politics meant "Worker vs Employer".
Worker vs Employer aren't actually 2 groups of people, unless you really consider corporations as people.
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.
