The Swedish Work Environment Authority decides on exemptions in three cases, namely where

1. There is no collective agreement at your place of work
2. There is a collective agreement, but it does not deal with the specific rule for which you are seeking an exemption.
3. There is a collective agreement, but you have negotiated and are unable come to an agreement. If you have a collective agreement at your place of work, you must first negotiate with the national union to seek a solution through the collective agreement.
