Offboarding – Checklist for an Orderly Employee Departure

Offboarding is all too often improvised. That creates serious problems for security — unreturned access rights and company equipment —, for legal compliance and documentation, and for company culture and staff morale: everyone notices how an organisation treats a departing colleague.

Phase 1: Following Receipt or Service of Notice

Check and document notice periods. Calculate statutory minimum notice under Section 86 of the Employment Rights Act 1996 (ERA 1996) alongside contractual notice terms, basing calculations on continuous service and the exact date notice was served. For dismissals, ensure fair statutory dismissal procedures are observed (adhering to the ACAS Code of Practice on Disciplinary and Grievance Procedures) and check for protected characteristics under the Equality Act 2010 or special protections (e.g. pregnancy, statutory maternity/paternity/adoption leave, or whistleblowing).

Involve employee representatives / trade unions. Where collective redundancy thresholds apply (20 or more redundancies within 90 days under Section 188 of TULR(C)A 1992) or where collective agreements/information and consultation bodies exist (under the ICE Regulations 2004), mandatory statutory consultation processes must be completed; failure to consult properly can result in substantial protective awards by an Employment Tribunal.

Decide on garden leave or PILON (Payment in Lieu of Notice). If invoking garden leave, verify that the employment contract contains an express garden leave clause. Clearly document whether the employee is required to take accrued statutory annual leave during this period, ensuring compliance with the statutory notice rules under Regulation 15 of the Working Time Regulations 1998 (giving notice of at least twice the length of the leave required to be taken). If making a PILON, check that contractual authority exists to avoid technical breach of contract claims.

Review post-termination restrictive covenants. Evaluate non-compete, non-solicitation, non-dealing, and confidentiality covenants. Ensure that covenants are reasonable in scope, geographical reach, and duration (typically no longer than 3 to 12 months) to remain legally enforceable under UK restraint of trade principles, or confirm in writing if any restrictions are being waived.

Phase 2: Handover

Plan knowledge transfer. Do not treat handovers as a last-day document drop, but as an active, structured process: ongoing workflows, key client and supplier contacts, open project deliverables, shared system credentials, and file archive locations.

Close out project time tracking. Record and approve all pending timesheet bookings and working hours — after the departure date, corrections become cumbersome, and the individual will no longer be available to verify time records. Accurate records are also essential for calculating National Minimum Wage compliance and holiday pay entitlements.

Designate a replacement / cover and configure cover assignments in your HR, CRM, and ticketing systems so that client and operational enquiries are seamlessly redirected.

Phase 3: Asset Returns and Access Revocation

For the departing employee's email inbox, implement a procedure compliant with the Information Commissioner's Office (ICO) Employment Practices Code and UK GDPR. Forwarding all incoming emails indiscriminately to a colleague is legally hazardous if private communications might be captured. Setting up an auto-responder redirecting senders to the nominated point of contact, followed by complete account archiving and scheduled deletion, is the safest and most compliant approach.

Phase 4: Final Payroll Settlement

Accrued untaken annual leave. Calculate statutory annual leave (5.6 weeks / 28 days pro-rata under Regulations 13 and 13A of the Working Time Regulations 1998) and any enhanced contractual leave accrued during the leave year up to the termination date. Under Regulation 14 WTR 1998, employers must make a payment in lieu of untaken statutory leave upon termination. Ensure correct holiday pay calculation rules are applied (incorporating regular overtime, commission, and allowances into normal remuneration where applicable).

Working time and TOIL balances. Any positive Time Off In Lieu (TOIL) or banked hours balance must be settled with final pay. Conversely, deductions for excess holiday taken or negative hours balances may only be made from final salary if authorised by a clear, pre-existing written contractual agreement or statutory provision in compliance with Section 13 of the Employment Rights Act 1996 (protection against unlawful deductions from wages).

Additional settlement items. Process pro-rata bonus or commission entitlements (subject to contractual "good leaver" provisions), lawful clawback of training costs under a valid, signed training agreement, and outstanding expense reimbursements.

Phase 5: Statements, HMRC Forms, and Documentation

Issuing the Form P45 promptly upon termination is a legal requirement under HMRC PAYE rules, enabling the departing employee to provide tax details to their new employer or the Department for Work and Pensions (DWP) without emergency tax code disruptions.

Phase 6: Post-Departure

Data retention and statutory erasure. Personnel files and digital HR records must be managed under strict statutory retention schedules:

• Payroll, PAYE, and National Minimum Wage records: Minimum of 6 years (under NMWA 1998 and HMRC requirements).
• Health and safety incident records / statutory registers: Minimum of 3 to 40 years depending on exposure types.
• General personnel files, performance appraisals, and disciplinary records: Typically retained for 6 years following termination (aligned with the Limitation Act 1980 for breach of contract claims). Once statutory retention periods expire, the UK GDPR requires that personal data be securely erased or anonymised.

Evaluate the exit interview. A structured exit interview provides candid feedback and operational insights into workplace culture, management practices, and turnover risks. To foster honesty, it should ideally be conducted by HR rather than the direct line manager.

Maintain alumni relations. Former employees are among your most authentic brand advocates and prime candidates for future recruitment programmes.
