well, everyone has different experiences, but just to make it clear, I was calculating ordinary salary during notice period into severance pay since in many companies it's essentially severance pay:

1. you get fired with 2 months notice period and they will tell you, you don't need to bother to come anymore = 2 months of severance, you can sit at home, look for job for 2 months with full salary

2. on top of this you will get also extra 2 months severance pay

so in total de facto 4 months of severance pay , but I understand shitty companies will expect you to work even during notice period (especially if they are firing you) and somehow expect you will be delivering same results, smarter companies know the reality when they are firing someone and just tell him not bother coming anymore, this was my case in last 1-2 jobs I've had more than 10 years ago when I was still employee (plus they wanted to give me 1 month severance pay, but I argued about years I worked there and certain operation practices which could be published, so got 2 months, unlike my less assertive colleagues), I'm nowadays contractor/freelance for companies outside Europe so no law protection for me

my wife is always employed as employee and got fired this winter under conditions I mentioned in point 1&2 and got 2+2 months after 1 year of work, two jobs ago she was fired without severance but didnt need to work during notice period

plus I've found funny mention of the 6 months COBRA as some benefit, you are covered by insurance in Europe regardless of your job status whether employed or unemployed you are always covered by universal healthcare

The European model will never be better than the U.S. one for productive workers like in tech. Tech workers in the U.S. have the same benefits as EU ones for three times the salary.
