(1) Work in excess of agreed working hours must not take place except in cases when there is an exceptional and time-limited need for it.(2) If in the case of some employees, the work exceeds the limit prescribed by the Act for normal working hours, the time in excess is regarded as overtime.(3) Before imposing work as referred to in this section, the employer shall, if possible, discuss the necessity of such work with the employees' elected representatives.(4) Overtime work must not exceed ten hours per seven days, 25 hours per four consecutive weeks or 200 hours during 52 weeks.(5) The employer and the employees' elected representatives in undertakings bound by a collective pay agreement may agree in writing upon overtime work not exceeding 20 hours per seven days, but that total overtime work does not exceed 50 hours per four consecutive weeks. Overtime work must not exceed 300 hours during 52 weeks.(6) The Labour Inspection Authority may on application in special cases permit total overtime work not exceeding 25 hours per seven days or 200 hours during 26 weeks. Records of the discussions cf. the third paragraph shall be enclosed with the application. If the undertaking applies for overtime within the framework of the fifth paragraph, the reason why the matter was not solved through an agreement with the elected representatives of the employees shall always be stated. When making its decision, the Labour Inspection Authority shall attach particular importance to the health and welfare of the employees.(7) Overtime work in excess of the limit laid down in the fourth paragraph may only be imposed on employees who, in each case, have declared their willingness to perform such overtime.(8) Total working hours must not exceed 13 hours per 24 hours or 48 hours per seven days. The limit of 48 hours per seven days may be calculated according to a fixed average over eight weeks, provided that the total working hours pursuant to section 10-5, second paragraph, and section 10-6, fifth paragraph, do not exceed 69 hours in any one week.(9) The employer and the employees' elected representatives in undertakings bound by a collective pay agreement may agree in writing to exceptions from the limit of 13 hours provided in the eighth paragraph provided, however, the total working hours do not exceed 16 hours per 24 hours. The employee shall in such case be ensured corresponding compensatory rest periods or, where this is not possible, other appropriate protection.(10) An employee shall be entitled to exemption from performing work in excess of agreed working hours when he or she so requests for health reasons or weighty social reasons. The employer is otherwise obliged to exempt an employee who so requests when the work can be postponed or performed by others without harm.(11) For overtime work a supplement shall be paid in addition to the pay received by the employee for corresponding work during normal working hours. The overtime supplement shall be at least 40 per cent.(12) The employer and the employee may agree in writing that overtime hours shall wholly or partly be taken out as off-duty time on agreed dates.
