I wonder if that's actually true - unionbusting is mostly an emotional issue for leaders and owners so I wonder if there's any calculation involved.
I've seen corporate HR got to insane (illegal) lengths to "stick it" to people trying to unionize - to the point of being severely fined.
So I wonder if anyone actually calculated financials here.
there’s also a dam breaking effect. if unionization starts kicking off again, that can be contagious. so companies are incentivized to “nip it in the bud”
