Last spring, it was announced that around ten percent of the 7,000 employees at Klarna would have to leave the company due to a tougher economic climate.

The Union shall not have been informed of the dismissals or had the opportunity to negotiate them.

- We believe that they have not fulfilled their obligations in the law on co-determination, says Martin Wästfelt.

According to the Union, it is unusual for unions to sue companies for violations of the law on co-determination.

- This is because the vast majority of companies in Sweden have collective agreements.

And those who don't have it usually choose to interpret the rules as we do, says Martin Wästfelt.

Klarna has two to three weeks to respond to the lawsuit.

If the parties do not agree, the case goes to the Labor Court.

SVT seeks Klarna for a comment.
