If you have a secondary employment it shall be reported! Secondary employment is any work carried out alongside an employee’s principal employment, and which is not attributable to private life. This applies regardless of whether the employment is permanent or temporary, paid or not. The type of secondary employment may be of importance when it is assessed whether the employment is permitted or not. Even extra work for SLU or for another public agency can count as secondary employment. As a general rule, secondary employment is permitted.
