It is not that common in Norway. It has at least been argued in the past that working your notice period is not just an obligation to employer if they want to enforce it, but a right for the employee on the basis that being walked out can affect your reputation by implying possible misconduct exactly because it has generally been uncommon in Norway.

I haven't worked in Norway for a long time, so haven't kept up to date on the current legal position. The typical argument used to be that if there were concerns over IP theft or sabotage, there were other ways of protecting against that - and indeed, insider risk is something companies need to deal with whether or not someone has been fired.
