Having experienced layoffs in both US and EU companies, the difference is massive. In my experience there is very little respect for "the human" being laid off in US companies
People literally would just disappear day to day. I've had several instances where I only found out a colleague had been fired because I tried to write them on Slack only to find that their account had been deactivated
Personally I felt constantly worried working in such an environment and I don't want to work for another US company again if I can help it
There are of course bad cases in the EU, but in my experience it's way less common than in the US
