And, the union doesn't claim to speak for all workers. It only claims to speak for its members, and to fight to protect all workers.
I'm not sure that changes much. To me, "BIPOC" is anything but inclusive. It's an acronym that apparently was used for about a month, by people of a very specific political ideology, and seems to be criticized by the very people this term is supposed to represent. [1]
And what does totalitarianism have to do with anything? I am all for putting a bit more power in employees' hands (esp. for issues where HR will throw an employee under the bus), but can we please keep the divisive political rhetoric out of it? Not shoehorn "BIPOC" and politically-charged language everywhere?
I am a "BIPOC", but I feel this rhetoric will be more effective with (mostly white) progressives/liberals, not the people it purports to represent.
