In Italy if you get fired (not if you quit voluntarily) it's mandatory by law to get 75% of salary for 104 weeks (but from the six month it will get reduced by a 3% monthly) plus the severance package is at least 6.9% of the yearly gross salary multiplied by the number of years worked there.

On top of that, most union contracts (97% of workers in the country) increase that amount of money that the company has to pay.

Finally, it's a bureaucratic mess. You can't just fire employees with an email sent Friday afternoon and expect to get the offices empty on Monday. In order to fire more than 5 employees over 120 days the company has to get agreement with unions (money incentive to resign; early retirement; higher and/or longer severance pay) and if it's doesn't get an agreement within 45 days it will need to get an agreement with the government (another 30 days) where need to pay at least a 5850 euro tax for each fired employee. So from the cuts announcement, workers have at least 2 months of full pay and full work.

The only way to fire employees "American style", "from today you're unemployed" in Italy it's bankruptcy (chapter 7) but proceeds from the liquidation Will be used to pay

First of all very clearly says up to 26 weeks. So I don't know where you're getting 30 from. The fact that it's even shittier for other people doesn't make this not shitty though.
