Anecdata: Spouse was let go from Salesforce in the January round of layoffs, after 2 years there. She received 6 months salary, was allowed to keep RSUs that would have vested within 90 days (which amounted to another ~2 months salary), and the company paid for COBRA for her and family for 6 months.
That was very generous, but it's not at all unheard of. There are people who were on her team who got more than 12 months. They had been there quite a bit longer.
I’ve been on the company’s side of a few RIFs lately, it’s not fun for anyone, and clearly worse for the employees. But even for brand new employees we do at least a month’s severance + health care etc. For many, it’s 90+ days. Unless your company is at urgent risk of bankruptcy, just be a normal human and spend the few extra dollars so a bad day is a as good as possible.
