Unfortunately way too much, some of the people who advocate for them the loudest are very political people of a particular polarization that makes a big deal about pronouns. Take this Google union I found from another comment here: https://alphabetworkersunion.org/. Take a look at what they have at the top of their homepage. The forth word is "BIPOC," towards the middle it says "believe in social justice." Those are polarizing political shibboleths.

Frankly, unions will not get off the ground without solidarity across worker political factions, and injecting polarizing ideology not strictly necessary for unionization does the same union-busting job as Google's consultants.
