Remaining part of parental leave to take place early 2014

This week I have received a letter from NAV, the Norwegian Labour and Welfare Administration (see previous posts on their repeated inability to deliver on what are my rights according to Norwegian law), confirming that they have accepted my application for parental leave in the beginning of 2014. Specifically, I will have graded parental leave (75 %) from January 1st 2014 to March 13th 2014. At the same time I have, for the first half of 2014, a 25 % position at University of Stavanger's Department of health studies.
