On Thursday morning, 5 A and B stood in the schoolyard with large posters that they made themselves.
The strike is their own initiative.
They say they had three different teachers in math this school year.
Now their mentor will stop and the students have had enough.
- It is an organizational issue.
I understand that it arouses feelings that a teacher you have had for a year is leaving, says deputy head of school in Sunne, Anna Ullenius.
Hear some of the students and the school principal tell more in the clip.
