An employee walks into your office and hands in their resignation, or you decide it is time to let someone go. Either way, the next question is almost always the same: how much notice is actually required? Getting this wrong can mean unpaid claims, awkward handovers, or losing a good employee's goodwill right when you need it most.

Notice periods sound simple but trip up even experienced employers, because the rules differ by contract, by role, by length of service and by country. This guide walks through what notice periods are for, how they are usually set, and how to handle the practical side when someone is leaving.

What a notice period is and why it matters

A notice period is the length of time between someone announcing they are leaving (or being told they are being let go) and their actual last day. It gives both sides breathing room: the employer time to plan a handover or start recruiting, and the employee time to wrap up work and, if resigning, prepare for their next move.

Notice periods exist for a practical reason, not just a legal one. Without them, businesses would face constant disruption every time someone left with zero warning, and employees could be dismissed on the spot with no chance to arrange their finances or find new work. The notice period is essentially a buffer that protects continuity on both sides.

It is worth remembering that notice obligations usually run in both directions. If an employee owes you notice when resigning, you typically owe them notice (or pay in lieu) when you end the relationship, unless it is a case of serious misconduct that justifies immediate dismissal. The specific rules for what counts as justified immediate dismissal vary a great deal by jurisdiction, so this is an area where local legal advice matters.

How notice periods are usually determined

There is rarely one single answer to "how much notice is required" because several sources can apply at once, and generally whichever gives the employee the most protection tends to win.

  • The employment contract: Most notice obligations start here. A well-drafted contract states exactly how much notice each side must give, and this is usually the first place to check.
  • Local labour law or statutory minimums: Many countries and regions set a legal minimum notice period, often scaling up with length of service. These minimums vary widely, so always check your local labour regulations and official government sources rather than assuming a figure.
  • Custom or industry practice: In some sectors and seniority levels, longer notice periods are standard practice even where the contract or law says less, particularly for senior or client-facing roles.
  • Collective agreements: Where unions or sector-wide agreements apply, they may set notice terms that override or supplement individual contracts.

If a contract sets a notice period shorter than the legal minimum in your jurisdiction, the legal minimum usually still applies, because the law is generally treated as a floor that contracts cannot go below. Always check your local rules before relying on contract wording alone.

Notice during probation periods

Probationary periods almost always come with shorter notice requirements than a confirmed role, and this is one of the most common sources of confusion. A contract might specify one week's notice during probation and one month afterward, for example.

This shorter notice exists because both sides are still assessing fit. It gives employers flexibility to end a mismatch quickly, and gives new employees an easier exit if the role is not what they expected.

Make sure your contracts spell out the probation notice period explicitly, and that managers know the exact date probation ends. A common mistake is treating someone as "still on probation" past the contractual end date, which can mean you owe the longer, post-probation notice period without realising it.

Who owes notice: resignation versus dismissal

When an employee resigns, they typically owe you the notice period stated in their contract or set by local law. If they leave without giving proper notice, some jurisdictions allow you to withhold certain payments or seek damages, though this depends heavily on local rules and the specific facts, so check before acting.

When you dismiss an employee for reasons other than serious misconduct, you usually owe them notice (or pay instead of notice) based on their length of service and contract terms. Longer-serving employees are commonly entitled to longer notice, reflecting the greater disruption to their life and finances.

Serious misconduct, sometimes called summary dismissal, is typically the one situation where notice obligations can be bypassed entirely. What qualifies as serious enough varies significantly by jurisdiction and is one of the riskiest areas to get wrong, so document everything and get local legal advice before treating a dismissal as "no notice."

Garden leave and pay in lieu of notice

Once someone is leaving, you generally have three practical options for how the notice period plays out.

  • Working notice: The employee continues working as normal through the notice period, handing over responsibilities and finishing projects.
  • Garden leave: The employee remains employed and paid, but is asked to stay away from work, often used when there is sensitivity around access to clients, data or colleagues during a resignation.
  • Pay in lieu of notice (PILON): The employment ends immediately, and the employee is paid the equivalent of their notice period as a lump sum instead of working it.

Whether you can use garden leave or PILON often depends on whether your contract explicitly allows it. Ending employment immediately and paying instead of allowing someone to work their notice, without a PILON clause in place, can in some jurisdictions create tax or legal complications. Check your contract templates and local advice before assuming you can pay someone out at will.

Sample PILON clause language for a contract: "The Company reserves the right to terminate employment immediately by making a payment in lieu of notice, equivalent to the employee's basic salary for the notice period."

What to do when someone hands in their notice

The moment an employee resigns, a few things should happen quickly and calmly.

  1. Acknowledge the resignation in writing and confirm the last working day based on their notice period.
  2. Check the contract for the exact notice length and whether garden leave or PILON options apply.
  3. Decide on a handover plan: what needs documenting, who takes over which responsibilities, and by when.
  4. Consider whether to start recruiting a replacement immediately, especially for roles that take time to fill.
  5. Confirm final pay, any accrued but unused leave, and other end-of-employment details in writing.

Starting the search for a replacement early matters more than most employers expect, because hiring rarely moves as fast as you want it to. Tools like Hyrewell can help here: candidates apply through a simple link, get automatically screened into a ranked shortlist, book their own interview slots, and receive an e-signed offer once you have chosen someone, which can meaningfully shorten the time between a resignation and having someone new in the seat.

Handling shorter notice or requests to leave early

It is common for a departing employee to ask if they can leave earlier than their contractual notice period, often because a new employer wants them to start sooner. You are not usually obliged to agree, but there is often room to negotiate.

Some options worth considering include releasing the employee early but still paying out the rest of the notice period, agreeing to a shorter notice period in exchange for a thorough handover before they go, or holding firm on the full notice period if the role is hard to cover quickly.

Sample response to an early-leave request: "We understand the new role has a tight start date. We're willing to release you two weeks early provided we have a completed handover document and you're available by phone for questions during the transition."

Whatever you agree, put it in writing. Verbal agreements about changed notice periods are a common source of later disputes over final pay and last working dates.

Common mistakes employers make with notice periods

  • No clear notice clause in the contract: Relying purely on assumed local minimums leaves both sides guessing, especially for senior roles where longer notice is expected.
  • Forgetting probation end dates: Applying the shorter probation notice period after probation has technically ended, which can breach the contract.
  • Treating PILON as automatic: Paying someone out and ending employment immediately without a PILON clause, which can create legal or tax problems depending on jurisdiction.
  • Skipping the paper trail: Not confirming resignation dates, handover expectations, or early-leave agreements in writing.
  • Delaying recruitment: Waiting until the last week of someone's notice to start looking for a replacement, leaving a gap in coverage.
  • Ignoring local law changes: Notice period rules and statutory minimums can change, so contract templates should be reviewed periodically against current local regulations.

Building better notice terms into your hiring process

The best time to think about notice periods is before you need them, not in the middle of a resignation. When drafting offer letters and contracts, be explicit about notice length for both probation and confirmed employment, whether PILON or garden leave applies, and what happens to unused leave or bonuses if someone leaves mid-cycle.

It also helps to standardise your offboarding process so that whoever resigns gets the same clear, professional handling: written acknowledgment, a documented handover plan, and a final pay breakdown. This consistency reduces disputes and protects your reputation as an employer, which matters for future hiring even when someone is on their way out.

Finally, revisit your contract templates periodically. Labour regulations around notice periods, especially statutory minimums tied to length of service, can change over time and differ by region if you employ people in more than one location. A short annual review with a local employment law advisor is a small investment that prevents costly surprises later.
