The frequency with which the salary is paid is usually determined in the employment contract. Unless agreed, the law stipulates that wages must be paid at least twice a month. Nevertheless, in Norway, it is usual to fix the payment of wages once a month. The date of payment of wages varies, but the standard system in the private sector provides for an arrears payment at the end of the month. When paying wages, the employer should provide the employee with a payslip that includes the wage specification, tax deductions and any other deductions.

Working hours are quite strictly regulated in Norway. The parties are free to a certain extent in determining the working hours, but the overall working time must not exceed nine hours within 24 hours and 40 hours within seven days. During the day, the time off from work must be at least 11 hours. For groups that are subject to more burdensome working time systems, such as shift work, work in a camp, night and Sunday working hours, a shorter weekly working time is set (38 hours per seven days for work that is carried out around the clock on general days and 36 days out of seven for work that is carried out around the clock all week). It is always possible to set shorter working times. Under collective agreements, the most common working hours are 37.5 hours per week.

The parties are free to determine the distribution of working time, i.e. the time of starting and ending working time. In principle, the employee should not work at night or on public holidays / weekends.

In the case of work exceeding the standard working time, the standard hourly wage with a minimum supplement of 40% must be paid.

Overtime work may not exceed ten hours in seven days, 25 hours in four consecutive weeks, and 200 hours in 52 weeks. However, the employer and employee representatives in an undertaking covered by a collective agreement may, on the basis of a written agreement, extend overtime work to 20 hours within seven days, but the total amount of overtime work may not exceed 50 hours for four consecutive weeks. However, overtime work may not exceed 300 hours in any 52-week period. In addition, in special cases, the Arbeidstilsynet [Norwegian Labor Inspectorate] may, on request, authorize up to 25 hours of total overtime in seven days and 200 hours in 26 weeks.

The total working time, the sum of normal working hours and overtime, may not exceed 13 hours in any 24 hours, or 48 hours in any seven days. The limit of 48 hours over seven days may be averaged over an eight week period. However, the employer and employee representatives in an undertaking covered by a collective agreement may, on the basis of a written agreement, grant an exception to the 13-hour limit within 24 hours, provided that the total working time does not exceed 16 hours in any 24-hour period.
