I know HN is mostly against regulation, but I'm very glad my country restricts mass firings, and particular stricter rules apply for companies that turn a profit.
If you're generating benefits, there should be very few reasons you need to let go people massively.
The Nordic countries provide income replacement and retraining instead. Labor market inflexibility locks out younger unproven workers.
Limit mass firings and you are also limiting mass hirings.
HN is very much pro regulations of all types.
I have a cousin in Belgium who was laid off following some restructuring and her severance was 52 weeks. Not out of the goodness of the company's hearts, but mandated by law since they gave no notice and she had accrued seniority. US labor laws are a joke in comparison.
