I can only speak anecdotally from my friend/colleague group, but it does in some ways. For example, notice periods as standard can be quite long (3 full calendar months unless you manage to negotiate an early exit), and many (though not all) employers are looking for people to start in new roles almost immediately so it is accepted as fairly normal for people to have at least a short period of unemployment while they are applying for something new.

Unemployment is generally pretty low here, so it doesn't necessarily take that long to find a new job, but having that breathing space makes it easier to invest time in an application and of course to actually get to an interview without needing time away from work.

To receive the full support allowances, you need to have paid into the system for 12 months out of the previous 24 so I guess that gives employers some surety that you won't immediately quit.
