I have read the entire law regarding the inter-play between employer and employee, commonly called Arbeidsmiljøloven (direct translation: Work Environment Law) of Norway, and I cannot see this woman's accusation being anywhere in there. I even read the entire old law (They have changed the wording and added a few words here and there, therefore they must exchange the whole law (Huh?))

Not once in my several readings and re-readings of this law did I see anywhere mentioning four years of substitution equals tenure. This leads me to think she was going by some local regulations, not the law, even if she said that it was in the law.

I have tried to keep an un-biased eye on the text of the law while reading it for the sake of this argument, and even re-read it several times, however, my conclusion is still the same: The law states no timeframe after which a substitute is given tenure regardless.
