europe is the worst of both worlds. there isnt really protection. and as the years go by it gets worse as our governments vote new law to reduce our protections. let me give you the example of france. when we join a company we can be fired during the first six months with very little real reason. when we want to leave the company we need to give a 3month notice (think about how happy is the new company knowing youll misss a quarter when some of those companies don't even plan their future well - just look GCP hiring freeze suddenly in the middle of a quarter while in a hiring spree one week before). when you get fired most of the time you will get unemployement. 55% of your salary (it is very good but when you plan your life around 100% salary it gets very very challenging to live on 55%). but only for the first 6 months (a new law that concerns mostly white collars...) then it will be degressive so that after a few months you out of luck. note that in europe you pay tax while you work so that you can be paid while unemployed... so the 6month degressive new law is pure stealing from the people and totally evil and because it hits only white collars workers most of the people don't talk about it because it concerns people that are 'well off' in the society while in reality policies like this are a total destruction of the middle class.

finding a new job you will compete with people that have this 3 month notice so most of the companies plan hiring around it. also if you are unemployed in europe it will look really bad during your interviews.

now compare that to USA. you give 2 week notice, job market is very fluid so you can likely find a new job 2 week after stay there a few months helping the company and then use that time to apply to a new job in a better company.

Obviously the french model might be better for low earners/blue collars that do not have a job security. but for everyone else it is really hard to move to another company, managers know that too so they dont need to carrot you into a raise or a promotion as much as they do in US.
