Norway's Arbeidsmiljøloven: Working Time Rules

Norwegian working time rules live in Chapter 10 of the Arbeidsmiljøloven (Working Environment Act, AML) of 2005, last substantially amended in 2017. Norway is not in the EU but follows the European Economic Area framework, which means the Working Time Directive applies through the EEA Agreement. The Norwegian rules are slightly tighter than the EU minimum in places (10-hour daily cap vs 13 in some EU countries) and more generous on protections for shift workers.

This post explains the Section 10 limits, the special rules for on-call and night work, and what Arbeidstilsynet (the Labour Inspectorate) checks during an inspection.

#Quick Reference

#The Core Rules

#Section 10-4: Standard Working Time

40 hours per week is the statutory maximum for regular working time. In practice, the dominant CBAs (LO/NHO, Hovedavtalen) set this at 37.5 hours.

Daily cap is 9 hours for regular working time; this can be extended to 10 hours with averaging arrangements approved by the worker or worker representatives.

For shift work and night work, the weekly cap drops: 38 hours per week for semi-continuous shift work (round-the-clock on weekdays) and 36 hours per week for fully continuous shift work that also runs on Sundays and holidays.

#Section 10-6: Overtime

Norwegian overtime rules are some of the strictest in Europe:

• Maximum 10 hours of overtime per single week
• Maximum 25 hours of overtime per 4-week period
• Maximum 200 hours of overtime per calendar year

Overtime requires "special and time-limited need" of the employer. Workers can refuse overtime where it would cause hardship. Overtime pay must be at least 40 percent premium.

Trade union agreements can raise the annual cap to 300 hours; the labour inspectorate can authorise up to 400 hours in special cases. The 200-hour baseline applies absent these arrangements.

#Section 10-8: Daily and Weekly Rest

• Daily rest: 11 consecutive hours per 24-hour period
• Weekly rest: 35 consecutive hours per 7-day period, preferably including Sunday

These align with the EU directive minimums.

#Section 10-9: Breaks

A break is required when the working day exceeds 5.5 hours. Breaks must total at least 30 minutes when the working day is at least 8 hours. The break may be required to be at least one hour for working days above 8 hours under sector arrangements.

The break is normally unpaid but counts against the daily limit if the worker remains at the workplace. CBA practice varies.

#Special Categories

#Shift Workers (Section 10-4(4))

Workers on rotating or night shifts have a tighter weekly cap (38 hours for semi-continuous shift work, 36 hours for continuous shift work that runs on Sundays and holidays) and stricter rest pattern requirements. Shift schedules typically need worker representative approval.

#Night Workers (Section 10-11)

A night worker is someone normally working at least 3 hours in the night period (21:00 to 06:00 by default; CBAs may vary):

• Average 8 hours per 24-hour period over a 4-week reference
• Free health assessments before assignment and at regular intervals
• Right to transfer to day work on medical grounds

#On-Call Workers (Section 10-4(2))

A unique Norwegian feature: time when a worker is on call (whether at home or at the workplace) is counted against working time at a fraction:

• On call at workplace: 100 percent counts as working time
• On call at home (standby duty outside the workplace): as a rule, at least one-seventh (1/7, about 14 percent) counts as ordinary working time
• This fraction can be adjusted by written collective agreement or by a decision of the Labour Inspection Authority

This unique scheme has been litigated in EU courts (the Matzak ruling has nuanced it) but Norwegian practice continues to use the fractional approach for non-residential on-call.

#Senior Executives

AML Section 10-12 exempts senior executives with autonomous decision-making power. Defined narrowly.

#Annual Leave (Ferieloven)

The Ferieloven (1988) provides:

• 25 working days of leave per year (5 weeks)
• 4 of those weeks must be taken consecutively in the main vacation period (1 June to 30 September)
• Holiday pay (feriepenger) is paid in advance at 10.2 percent of last year's gross salary (12.5 percent for workers over 60). The 10.2 percent base rises to 12 percent under the 5-week CBA entitlement

The 5-week minimum is higher than the EU directive's 4 weeks. Most Norwegian workers take 5 to 6 weeks, including CBA additions.

#Record-Keeping

The AML itself does not specify recording requirements as explicitly as the EU directive demands. The 2005 statute requires employers to "ensure" working time compliance, which has been interpreted to require records.

After the 2019 ECJ CCOO ruling (which applies to Norway through the EEA Agreement), Arbeidstilsynet published guidance in 2020 confirming the duty:

• Daily start and end of working time per worker
• Breaks taken
• Overtime worked, with category
• On-call time tracked separately

Records are kept under the Bokføringsloven (Bookkeeping Act) for 5 years. Workers and their representatives can request the records at any time.

In 2022, Arbeidstilsynet issued an updated inspection criterion stating that pure monthly summaries no longer satisfy; daily-level records are required.

#The Arbeidstilsynet

Arbeidstilsynet (the Labour Inspection Authority) enforces the AML. It has wide powers:

• Inspect any workplace without notice
• Require production of records on demand
• Issue immediate halt orders for severe risks
• Refer cases to the police for criminal prosecution

Penalties under AML Chapter 18:

Most inspections result in pålegg (orders) requiring remediation rather than immediate fines, with fines escalating if the order is ignored.

#Practical Compliance Checklist

1. Establish the applicable CBA. With 70 percent of private-sector workers under CBAs and effective sector coverage close to 100 percent, most employers operate under one.
2. Track daily start, end, and breaks for every worker. Post-2022 inspection guidance requires daily-level records.
3. Separate overtime by category. Single week, 4-week period, calendar year. Each has its own cap.
4. Document on-call time correctly. Use the right fraction for the worker's response-time profile.
5. Honor the 11-hour daily rest and 35-hour weekly rest. Schedule them explicitly.
6. Retain records for 5 years (Bookkeeping Act floor). Even where the AML doesn't expressly require it.

#Common Questions

Are senior managers exempt? Only those genuinely autonomous, narrowly defined. Department managers are not exempt.

What is the difference between AML and CBA rules? The AML is the statutory floor. CBAs typically improve on it (37.5-hour week, 5 weeks of leave, additional breaks). Always read both.

Can I require workers to be on call? Yes, but on-call time counts against working time at the fractional rates in Section 10-4(2). Excessive on-call can trigger overtime caps.

Are there Sunday work restrictions? Sunday work is restricted by the AML Section 10-10 to defined cases (healthcare, security, transport, etc.). CBA may add restrictions.

Are the 25 days of leave separate from public holidays? Yes. Norway has 11 public holidays plus 2 fixed leave days (May 1 and May 17). These are separate from the 25 working days.

#Summary

• The Arbeidsmiljøloven sets a 40-hour weekly cap, 9-hour daily, 11-hour daily rest, 35-hour weekly rest
• Overtime tightly capped: 10/week, 25/4-week, 200/year baseline
• On-call time counts fractionally against working time
• 25 working days of leave under the Ferieloven (4 must be consecutive in summer)
• Records required daily; retained 5 years under Bookkeeping Act
• Arbeidstilsynet enforces; fines up to NOK 5,000,000 in serious cases
