But they do that too everywhere. I'm Norwegian. I've been a co-founder of companies both in Norway and the UK. I see little evidence that it makes all that much difference. On one hand you do take a somewhat greater risk in terms of hiring in Norway, but conversely the ability to fire much more easily does not get exercised much. Of course that's no help for those who end up being affected.

On the opposite end of the spectrum, in Norway not only is it harder to fire someone, but terminating an employment contract is normally with 3 months mutual notice. So you risk bad hires, but you also don't risk essential staff members disappearing overnight very often, as serving out the 3 months notice is normal and expected. That makes companies with small teams less vulnerable in that respect.

Overall I don't really know if it makes much difference to employers. I hasn't seemed like that for me. But it makes a big difference for employees.
