Norway sits outside the EU but implements the EU Working Time Directive through its EEA membership. The primary law is the Working Environment Act (Arbeidsmiljøloven) - Act No. 62 of 17 June 2005. For most employers, this act plus any applicable collective agreement defines the limits of what you can ask.
The Standard
9 hours per day, 40 hours per week - that's the statutory maximum for normal working hours. Most Norwegian workers covered by collective agreements work 37.5 hours per week, which is the standard in the public sector and most major private sector collective agreements.
This distinction matters. If your employees are covered by a 37.5-hour agreement, overtime kicks in at 37.5 hours, not 40. Scheduling to 40 hours "because that's the legal limit" is a mistake that will cost you overtime supplements.
Overtime Limits - Norway's Tight Caps
Norway has stricter overtime limits than most EU countries:
- 10 hours of overtime per week
- 25 hours of overtime per 4 consecutive weeks
- 200 hours of overtime per year
These are hard caps. An employee cannot agree to exceed them individually. If a Labour Authority inspector finds a pattern of overtime exceeding these figures, the employer is in violation - employee consent is not a defence.
With a collective agreement, the cap can be raised:
- Up to 20 hours per week
- Up to 50 hours per 4 consecutive weeks
- Up to 400 hours per year
A combined limit also applies: total working time (normal hours plus overtime) cannot exceed 69 hours per week for any individual employee.
Overtime Pay
The statutory minimum overtime premium is 40% above the normal hourly rate. This applies from the first overtime hour. Collective agreements often set it higher - 50% is common, and some agreements pay 100% for overtime on public holidays.
You cannot substitute time off for the overtime premium without the employee's written consent. And if you do give time off instead of pay, the time off must equal the hours worked plus the 40% premium - so 1 overtime hour = 1.4 hours off.
Rest Periods
The Working Environment Act sets these minimums:
- 11 consecutive hours between shifts
- 35 consecutive hours of weekly rest per 7-day period
Night work has additional constraints. Regular night work (defined as work between 21:00 and 06:00) requires justification, and night shift workers are entitled to extra protections including health checks.
Enforcement and Penalties
The Norwegian Labour Inspection Authority (Arbeidstilsynet) enforces the Working Environment Act. Its powers include:
- Compliance orders (pålegg) - binding instructions to correct violations
- Administrative fines (overtredelsesgebyr) - up to 15 times the court fee (about NOK 2,000 per violation in minor cases, up to several hundred thousand NOK for serious or repeated breaches)
- Police referral for criminal prosecution - the Act provides for fines or up to 2 years imprisonment for intentional or grossly negligent violations
In practice, Arbeidstilsynet focuses on construction, hospitality, cleaning, and transport. These sectors see routine checks, often without advance notice.
The 37.5 vs 40 Problem
This is the most common issue for employers hiring across different sectors or bringing in staff from abroad. Someone used to a 40-hour country comes to work in Norway, the contract says 40 hours, and the collective agreement says 37.5. The employer thinks overtime starts at 40. The law says it starts at 37.5. That's 2.5 hours of unpaid overtime every week - and over a year, that becomes a significant liability.
Before you set your schedules, know: what does your applicable collective agreement say about normal hours? That number - not the statutory 40 - is your overtime threshold.
Rezano's shift scheduling lets you set custom weekly norms per employee group, so overtime calculations use the right threshold from day one. Real-time overtime reports flag weekly and 4-week totals before you hit the hard caps. Setup takes under 10 minutes. Try it at rezano.lv.
