Were I come from 4 months is the bare minimum. To be fair, you do not get your full salary but a reduced amount; however depending on the conditions that can extend up to 2 years.

Difference here is that it is not the company itself paying you that money but it is rather a government system which is payed directly by the workers.

It's a system which is not advantageous if you never lose your job, since you have to pay for it regardless; but comes very handy if you ever end up needing it.

The company also has to pay you 20-33 days of salary for every year you've been working there.
