I don't think any of these nutters have experienced the things they rail against. I'm not in the US, but from where I'm standing you guys haven't had any of that stuff since before Reagan.
DEI was policy during the Biden admin. It basically boiled down to employees having to take a yearly training telling us to respect coworkers backgrounds/identities and pronouns. It's not a bad thing and it sure as fuck didn't kill GameStop.
That really depends, a lot of orgs took it way too far by having hiring quotas and whatnot.
Our DEI thing was pretty straightforward. We already do something in the on-boarding process about psychological safety, so we just added some optional DEI sessions w/ free lunch where minorities would talk about their life story and struggles related to being a minority. That's it, and it was really enjoyable.
But yeah, it's completely unrelated to why Gamestop is selling stuff off. Their business is failing due to natural shifts in consumer spending patterns (who goes to gamestop to buy games anymore?), so they need to scale back.
