Probation and Notice Period in Norway: A Practical Guide

Standard probation and notice periods in Norway

In Norway the employment relationship is governed by the Working Environment Act, which sets the baseline for both prøvetid og oppsigelsestid.
A probation period (prøvetid) may be agreed for up to six months; three months is the most common length in permanent contracts. During this time either party can end the agreement with a one-week notice, unless the contract states a longer notice.

Notice periods (oppsigelsestid) are tied to length of service. After the first year of employment the statutory minimum is one month. After five years it rises to two months, and after ten years to three months. These are the defaults; many collective agreements in the oil & gas, maritime and tech sectors negotiate longer periods, especially for senior or specialist roles.

Sector variations matter. In the Stavanger oil region, collective agreements often stipulate a two-month notice after three years of service, reflecting the longer hand-over times on offshore projects. Maritime employers may require a three-month notice for captains and engineers because certification hand-overs are regulated. Tech companies in Oslo frequently keep the statutory one-month notice but may offer a longer period as a retention benefit.

To verify the exact rules that apply to you, first read the employment contract. Look for a clause titled “prøvetid” or “oppsigelsestid”. If the contract refers to a collective agreement, locate that agreement on the employer’s intranet or on the relevant industry portal. The agreement will list the default lengths and any sector-specific extensions. Knowing where the rule lives prevents surprises when you hand in your resignation.

How contracts and collective agreements can modify them

While the law provides a floor, contracts and collective agreements can raise (or, in rare cases, lower) the ceiling for both probation and notice periods.

• Shortening probation – Some employers offer a six-week prøvetid for highly experienced hires, arguing that the candidate’s track record makes an extended trial unnecessary. If you negotiate a shorter probation, make sure the contract explicitly states the new end date; otherwise the default six-month period may still apply.

• Extending probation – A clause may allow the employer to extend the prøvetid by up to three months after a performance review. This is legal only if the original contract mentions the possibility of extension and the employee is informed in writing before the original period ends.

• Negotiated notice periods – Senior engineers, project managers, or consultants often negotiate a two-month notice regardless of tenure. The contract must spell out the agreed notice and any conditions (e.g., “provided the employee has fulfilled all hand-over obligations”).

• Temporary vs. permanent contracts – Fixed-term contracts (midlertidig) typically end on the agreed end date without a notice period, unless the contract includes a termination clause. However, if a temporary contract is converted to permanent, the prøvetid may restart, and the notice period will be calculated from the new start date.

Always cross-check the contract language with the relevant collective agreement. If the agreement provides a longer notice than the contract, the longer term prevails. When in doubt, ask HR for clarification and keep the written response for future reference.

Calculating realistic start dates for your new role

When you decide to switch jobs, the earliest possible start date is not simply the day you hand in your resignation. You need to add the agreed notice period to any remaining probation time, then factor in hand-over tasks and any required approvals (e.g., security clearance for offshore work).

Step-by-step calculation

1. Identify the notice period – Look at your contract or collective agreement. Note whether it is one, two or three months, and whether any extension clause applies.
2. Check remaining probation – If you are still within prøvetid, add the remaining weeks or months to the notice period. For example, a six-month probation with two months already elapsed leaves four months of prøvetid.
3. Add hand-over time – Most employers expect a hand-over document and a brief knowledge-transfer meeting. Allocate at least one week for this, more for technical roles.
4. Consider approvals – Certain sectors (oil, maritime, security-sensitive tech) require internal sign-off before you can leave. Add another week if you know the process takes time.
5. Create a timeline – Plot the dates in a simple spreadsheet: column A = “Event”, column B = “Date”. Include resignation submission, last working day, hand-over completion, and earliest start date for the new employer.

A practical example: Anna, a project engineer in the energy sector, has a two-month notice after three years of service and a remaining prøvetid of two months. She submits her resignation on 1 May.

• Notice ends : 1 July
• Remaining probation ends : 1 July (coincides)
• Hand-over week : 2 – 8 July
• Approval week : 9 – 15 July
• Earliest start : 16 July

By visualising the timeline, Anna can tell her prospective employer that she will be available from mid-July, not early June as a naïve calculation might suggest.

Common mistakes to avoid

Switching jobs is a delicate process, and a few recurring errors can delay your start or even jeopardise the new offer.

• Assuming the statutory notice applies – Never rely on the default one-month notice without confirming the contract or collective agreement. Many sectors have longer negotiated periods that will automatically extend your exit timeline.

• Overlooking probation extensions – If your contract allows the employer to extend prøvetid after a performance review, you must treat the extension as part of your notice. Ignoring it can lead to a surprise “you still have three months left” situation.

• Failing to communicate start dates early – As soon as you receive a concrete offer, inform the new employer of your calculated earliest start date. If you wait until the final interview, the recruiter may assume you can start sooner and later be forced to renegotiate.

• Not documenting hand-over agreements – A verbal hand-over plan is easy to forget. Write a brief hand-over checklist and get a signature from your manager. This protects you from being blamed for unfinished tasks after you leave.

• Leaving out the probation clause in your resignation letter – Your resignation letter should state the notice period you are giving and reference the remaining probation, e.g., “I hereby give two months’ notice as required by my contract, with the remaining two months of probation concluding on 30 June.” This makes your intent clear and avoids misinterpretation.

By ticking these items off, you keep the transition smooth and maintain a professional reputation—an important factor in Norway’s close-knit industry networks.
