Employers are never going to get this right. Amazon specifically (and obviously they're not alone) is looking at a huge financial impact to "doing the right thing" here. Yes, we'd all want our employers to take this kind of safety seriously, and a few will, but most of them won't either because they don't care or because they're worried their competitors don't. Bezos isn't any different than anyone else here, really. Maybe someone will get to him to be kind, maybe they won't, but for employees that's just not something that's ever going to be a security guarantee.
Realistically, governments are the only entities capable of providing this kind of security in extremis. Employers, at best, get this right (due to competetive pressure) during steady state situations. When the world blows up, they can't help.
