Employee Leaving? UK Employers’ Guide to Notice, Pay, Handover, Risks

When an employee leaves, the way you handle their exit matters. Get it right, and you protect your business, your team morale and your reputation. Get it wrong, and you could face disputes, data risks, client disruption or even legal claims.

In this guide, we’ll walk through a clear, employer-friendly process for managing an employee leaving under UK law - from notice and pay to garden leave, company property, confidentiality and restrictive covenants. We’ll also cover common tricky scenarios like resignations made in the heat of the moment, unauthorised absence and gross misconduct.

Setting up your legal foundations now means you can handle departures smoothly and stay protected from day one.

What Should You Do First When An Employee Resigns?

Start with a simple, structured process. It keeps things calm, professional and compliant.

1) Ask For Written Confirmation

Request a short resignation email or letter setting out the intention to resign and the intended last day. This reduces misunderstandings and gives you a clear record.

2) Check The Contract And Policies

Confirm the notice period, any garden leave rights, payment in lieu of notice (PILON), bonus or commission rules, and post-termination restrictions. These should be set out in the Employment Contract and your Staff Handbook.

If your template feels dated or sparse, it’s wise to refresh your Employment Contract and workplace policies so future exits are easier to manage.

3) Acknowledge The Resignation

Send a brief acceptance letter or email. Include:

• The last working day (based on the contractual or statutory notice period)
• Any garden leave arrangements or whether you’ll use PILON
• Return-of-property and data handback steps
• Holiday entitlement position (taken vs outstanding)
• The exit interview date (optional but useful)

4) Plan Handover And Access

Agree a practical handover timeline. Identify key clients, projects and passwords that need transferring, and set deadlines. Schedule when systems access will be limited and then fully removed after the last day.

5) Keep Communication Professional

Tell the team the person is leaving and clarify roles and responsibilities during the transition. Calm, consistent messaging avoids rumours and helps you maintain momentum.

How Do Notice Periods, Garden Leave And PILON Work?

Notice is usually set out in the contract. If there’s no contractual notice, statutory minimum notice applies under the Employment Rights Act 1996 (for employees, typically one week after one month of service, increasing with length of service). You can request the employee works the notice period - but there are other options.

Garden Leave

If your contract allows it, you can place the employee on garden leave. They remain employed (and paid) but do not work, do not access systems and generally stay away from customers and suppliers. This protects confidential information and relationships while you transition responsibilities.

Payment In Lieu Of Notice (PILON)

If a PILON clause exists, you can end employment immediately and pay the employee for the notice period instead. PILON can be helpful if you want a swift exit where continued presence is disruptive or risky.

Resignations In The Heat Of The Moment

If someone resigns under pressure or in a highly emotional situation, consider giving them a short cooling-off window. Tribunals sometimes look unfavourably on snap decisions. If they ask to retract their resignation within a reasonable time, weigh up the risks and fairness before you decide. For a structured approach, see guidance on retracting a resignation.

What Pay, Holiday And Deductions Are Lawful When An Employee Is Leaving?

Final pay is where issues commonly arise. Staying aligned with the Employment Rights Act 1996 and the unlawful deductions rules is key.

Final Salary And Benefits

Pay for all hours worked up to the last day, plus any contractual entitlements that have accrued. Check how benefits, allowances and regular commission are treated on termination under the contract.

Holiday Pay

Under the Working Time Regulations, employees are entitled to be paid for accrued but untaken statutory holiday on termination. If they took more holiday than accrued, you may deduct the excess if your contract expressly allows it and the deduction is lawful.

Expenses

Ask for all expense claims to be submitted by a set deadline, with receipts. Ensure policy compliance and process agreed reimbursements in the final payroll.

Bonuses And Commission

Follow the contract rules on eligibility and timing. If the scheme is discretionary, apply objective criteria consistently to avoid allegations of unfairness or discrimination. Where there are clawback provisions, confirm they are clearly drafted and enforceable before relying on them.

What Deductions Can You Make?

Deductions from wages are tightly regulated. Generally, you can only deduct if:

• The employee agrees in writing (usually via the contract)
• It’s required by law (e.g. tax)
• It’s a genuine overpayment of wages

To stay compliant, revisit your approach to wage deductions and keep clear contractual wording. If you discover an overpayment scenario, there are specific risks and options - our guide to wage overpayments explains how to handle recovery fairly.

How Do You Protect Data, Clients And Know‑How When A Leaver Exits?

Protecting your business assets during offboarding is as important as calculating pay. Focus on information security, client continuity and enforceable protections.

Return Of Property And Access Removal

Issue a checklist covering laptops, phones, keys, ID cards, documents, designs, prototypes and any storage media. Disable access to email, cloud storage, code repositories and CRM systems on the last day (or earlier if risk is high). Remember backups and shared credentials too.

Confidentiality

Most contracts have a confidentiality clause that survives termination. Remind the leaver of their ongoing obligations and the potential consequences of misuse. If you suspect information leakage or unauthorised downloads, act quickly - consider your options under your policies and take steps outlined in guidance on confidentiality breaches at work.

Restrictive Covenants And Non-Competes

Well-drafted post-termination restrictions (like non-solicitation of clients, non-poaching of staff and limited non-competes) can protect your relationships. Enforceability depends on reasonableness in scope, duration and geography.

If you rely on these protections, ensure they’re tailored to the role’s genuine business interests. It’s wise to review how restrictive covenants are calibrated and how non‑compete clauses are drafted before you seek to enforce them.

Personal Data And UK GDPR

Under the Data Protection Act 2018 and UK GDPR, you must manage personal data lawfully. Limit who can access client and employee data during handover, and maintain a clear record of what’s retained and why. If a departing employee submits a subject access request (SAR), follow statutory deadlines and processes. Keep your privacy and HR policies aligned with your retention schedule.

How Do You Handle Tricky Leaver Scenarios (AWOL, Misconduct, Disputes)?

Most exits are smooth, but some need a careful, legally sound approach.

Unauthorised Absence Or “No-Show” Resignations

If someone stops attending work without explanation, follow your absence policy: try to contact them, keep records and warn of consequences. Persistent unauthorised absence can lead to disciplinary action and potentially dismissal, but follow a fair process that’s consistent with your policies and the ACAS Code of Practice. For a structured process, see our guidance on unauthorised absence.

Gross Misconduct Near The End Of Employment

If you identify serious misconduct (e.g. theft of data or violent behaviour) during notice, you may be able to dismiss summarily. Ensure you investigate fairly, suspend only where reasonable and necessary, and follow your disciplinary procedure. Suspension isn’t a punishment - use it carefully; this overview of employee suspension rules covers risks and best practice.

Resignation Versus Dismissal Risks

Be consistent in documentation and timing. If you want to end employment instead - for performance or conduct reasons - you must follow a fair process. This includes proper investigation, warnings (where appropriate), and a chance to respond. For a full framework, see our employer checklist for ending an employment contract fairly.

Discrimination And Whistleblowing

Take extra care if the leaver has raised grievances, health conditions or protected disclosures. The Equality Act 2010 and whistleblowing laws prohibit victimisation. Keep decisions evidence-based and well documented.

What Documents And Processes Should Employers Have In Place?

The smoother your templates and policies, the easier every exit becomes. At minimum, make sure you have the following foundations in place.

Employment Contract

A robust, tailored contract that sets clear notice periods, PILON, garden leave, return-of-property, confidentiality, IP ownership, and post-termination restrictions makes all the difference. If you engage consultants, use a separate, appropriate consultancy agreement rather than repurposing employment terms.

Staff Handbook And Policies

Align your disciplinary, grievance, absence, IT/security and data protection policies with the ACAS Code and UK GDPR. These policies guide how you handle issues like AWOL, suspension, investigatory meetings and handover rules.

Offboarding Checklist

Create a practical checklist that covers:

• Written resignation and acceptance
• Notice period, garden leave or PILON decision
• Handover plan: clients, projects, passwords, files
• Access changes and account closures
• Return of property and data confirmation
• Holiday pay and final payroll calculations
• Reminder of confidentiality and restrictions
• Reference approach (if you provide them)

References And Communications

Have a consistent references policy. If you provide references, stick to factual, non‑defamatory information and ensure data accuracy. Internally, plan how and when you’ll announce departures and who will field client communications.

Data And Records

Check your retention policy to ensure you’re keeping ex‑employee records for the right timeframes. Limit access to personal data during handover and make sure devices are wiped and redeployed securely.

Employer FAQs About Employees Leaving (UK)

Do Employees Have To Give Notice?

Yes, if there’s a contractual notice period. If not, statutory minimums apply once they’ve been employed for at least one month. You can always agree a different date by mutual consent.

Can We Insist On Garden Leave?

Only if the contract gives you the right. Without a garden leave clause, placing an employee on paid leave may risk breaching the contract. This is one reason tailored contracts are essential.

Can We Deduct Money For Unreturned Property?

Only where there’s a clear, signed agreement permitting such deductions, and the deduction is reasonable and compliant with unlawful deductions rules. If in doubt, seek advice before deducting.

Can We Stop An Employee Joining A Competitor?

You can’t stop lawful competition generally, but you may enforce reasonable restrictive covenants that protect legitimate business interests, such as client connections or trade secrets. Scope and duration must be no more than necessary.

What If A Leaver Asks To Retract Their Resignation?

Consider the context, timing and any cooling-off you’ve allowed. If the resignation was impulsive and they request retraction promptly, a refusal may carry risk - assess fairly and document your decision-making. The guidance on retracting a resignation covers key factors.

Step-By-Step: A Compliant Offboarding Timeline

Step 1: Confirm The Resignation In Writing

Receive the resignation email, check the contract, and send your acceptance with last day, garden leave/PILON and handover details.

Step 2: Agree Handover And Limit Access

Plan knowledge transfer, client communication and staged access restrictions where appropriate. Set deadlines and owners.

Step 3: Calculate Final Pay Correctly

Work out salary to termination date, holiday pay, approved expenses and any lawful deductions. Double‑check scheme rules for bonus/commission.

Step 4: Collect Property And Data

Retrieve devices, keys and documents. Securely wipe and confirm destruction or return of any copies, including personal devices if BYOD was used (ensure your policy supports this).

Step 5: Remind About Confidentiality And Restrictions

Send a short reminder of continuing obligations, with copies of relevant clauses. If you have concerns, monitor client churn and access logs.

Step 6: Close Out Communications

Notify internal stakeholders and selected clients. Set email forwarding and update voicemail/CRM ownership. Hold an exit interview if appropriate.
