> does US have an unemployment plan. how long and how much do you get ?

Each state has unemployment insurance. In most cases, the benefit amount per week/month puts you around the federal poverty line for an individual. No state has a severance requirement (although some do require your PTO balance be paid out as wages).

Yes. It depends on your salary, but given the current covid crisis, most airbnb technical employees are eligible for around $4200 per month for 26 weeks.

Yeah so severance is what you get from the company directly.

That counts as your usual pay. So during that time you don't get 'unemployment'. After the severance runs out then you collect unemployment, how much that is varies state to state.

then it's a little different in europe (afaik), you get your severance, it's one time payment but it's usually not that big. and you can right away get your unemployment payment. the length and the amount depends on how much have you worked and the pay you had. the one does not depend on the other.
