Termination of employment is the legal term for the moment an employment relationship comes to an end. In the UK, termination of employment is an umbrella concept: it covers every way a job can finish, from resignation and mutual agreement to dismissal, redundancy and retirement. For employees, the way a termination of employment is handled determines notice pay, final wages, references and the right to bring tribunal claims. For employers, getting it wrong can turn an ordinary exit into an unfair dismissal or wrongful dismissal dispute. This guide explains how termination of employment works in England and Wales: the main routes by which employment ends, the rules on notice and the effective date of termination, and what should happen on the employee’s last day.
What Is Termination of Employment?
A termination of employment happens when the contract between an employer and an employee comes to an end, for any reason. Employment does not end simply because someone stops turning up: in UK law, there must be a legally recognised way for the relationship to end, and the date it ends matters. That date, known as the effective date of termination, fixes time limits for tribunal claims, decides whether notice was properly given and anchors calculations for redundancy pay and holiday pay.
Understanding termination of employment matters on both sides of the desk. An employee needs to know what notice they must give, what pay they are owed and whether the way they were let go gives them a claim. An employer needs a clean, documented process that ends the contract without creating fresh liabilities. The rest of this guide walks through each of those points in turn.
The Main Ways Employment Can Come to an End
There are several distinct routes by which a termination of employment can happen in the UK. The route matters because it determines which rights and obligations apply.
1. Resignation
When an employee chooses to leave, they resign. A resignation should normally be in writing and give the notice required by the contract. Once a resignation is clearly communicated and accepted, it generally cannot be withdrawn without the employer’s agreement, so employees should think carefully before resigning in the heat of the moment. Employers, in turn, should not treat an ambiguous statement (“I might as well leave”) as a resignation without checking what the employee actually meant.
2. Dismissal
A dismissal happens when the employer ends the contract. A forced dismissal — an involuntary end to employment at the employer’s instigation — is the most heavily regulated route. Under the Employment Rights Act 1996, a dismissal can be fair only if the employer has one of five potentially fair reasons — capability, conduct, redundancy, illegality, or some other substantial reason — and follows a fair procedure, usually in line with the Acas Code of Practice. Dismissal without a fair reason or a fair procedure can lead to an unfair dismissal claim, while dismissal in breach of the contract’s notice terms can lead to a wrongful dismissal claim.
3. Redundancy
Redundancy is a form of dismissal where the employer’s need for employees to do particular work has ceased or diminished — for example, after a business closure, a workplace closure or a reorganisation. Employers must consult affected employees (and, for 20 or more proposed redundancies, consult collectively), use a fair selection process and consider suitable alternative employment. Employees with at least two years’ continuous service are entitled to statutory redundancy pay, calculated from age, length of service and weekly pay subject to the statutory cap.
4. Mutual Agreement
Sometimes both sides agree that the employment should end. A negotiated exit is often documented in a settlement agreement, under which the employee receives an agreed financial package and waives specified tribunal claims after taking independent legal advice. Our guide to employment settlement agreements explains the conditions that make such agreements binding.
5. Expiry of a Fixed-Term Contract, Retirement and Other Routes
When a fixed-term contract expires without renewal, the law treats that as a dismissal, so the same fairness rules apply. Retirement at a chosen date is a resignation in legal terms, unless the employer forces retirement, which counts as a dismissal. In rare cases, employment can end through frustration — for example, where long-term illness makes performance of the contract impossible — but tribunals treat this argument with great caution.
How to Terminate Employment Lawfully: Notice and the Effective Date of Termination
To terminate employment cleanly, notice must be given properly and in good time. The contract usually sets the notice period; where it does not, statutory minimum notice under the Employment Rights Act 1996 applies. Once an employee has a month’s service, the employer must give at least one week’s notice, rising by one week per year of service after two years, up to a maximum of twelve weeks. An employee who has a month’s service must give the employer at least one week’s notice in return. Many contracts require longer, and the longer period is the one that counts.
Notice should be given in writing, state the last day of employment clearly and be delivered so there is proof of receipt. Employers who want the employee gone immediately can use a contractual payment in lieu of notice (PILON) or garden leave clause — but only where the contract allows it. Dismissing without notice is lawful only for gross misconduct, and even then the employer must be able to justify that the conduct was serious enough.
The effective date of termination (EDT) is the date the contract actually ends. Where notice is given by letter, the EDT is normally the date the employee reads it, or has a reasonable opportunity to read it. Getting the EDT right is critical: it starts the clock for employment tribunal claims, which in most cases must begin with Acas early conciliation within three months less one day of the EDT. The EDT also anchors redundancy pay calculations and the two-year qualifying period for unfair dismissal rights.
What Happens on the Last Day of Employment
The termination of employment triggers a series of practical obligations. On or before the last day, the employer should confirm the final pay arrangements in writing and pay everything owed through the final payroll: outstanding wages, overtime, commission, bonuses that have vested and payment for accrued but untaken statutory holiday under the Working Time Regulations 1998. An itemised payslip must be provided, and the employee should receive their P45 once the final payroll has run.
Company property — laptops, phones, keys, passes — should be returned, and access to systems withdrawn. Many employees are entitled to a reference on agreed terms, and it is worth settling the wording before the departure is announced. Restrictive covenants in the contract, such as non-compete and non-solicitation clauses, continue to bind the employee after the termination of employment unless they were waived, so both sides should be clear about what they cover.
Employment Termination Payments: Meaning, Tax and the £30,000 Rule
The employment termination payment meaning is specific in UK tax law: an employment termination payment is a payment made in connection with the end of employment that is not otherwise taxable as earnings — for example, an ex gratia payment or genuine compensation for loss of office. It is distinct from wages, notice pay and accrued holiday pay, which are always taxed as earnings through PAYE.
The headline tax rule is the £30,000 exemption: the first £30,000 of a genuine employment termination payment can be paid free of income tax under section 401 of the Income Tax (Earnings and Pensions) Act 2003. Anything above £30,000 is taxable. Since April 2018, however, the post-employment notice pay (PENP) rules have narrowed the exemption: the part of a termination payment that represents basic pay for any unworked notice period is now treated as earnings and taxed in full, even where the employee was dismissed without notice. Employer National Insurance contributions also apply to termination payments above £30,000. Because the boundary between taxable earnings and exempt termination payments is easy to get wrong, both employers and employees should take advice before agreeing the figures.
Related Guides on Ending Employment
Termination of employment is the umbrella; these guides cover the most important branches in detail:
- Unfair dismissal: when a dismissal lacks a fair reason or a fair procedure, and how tribunal claims work.
- Wrongful dismissal: dismissal in breach of contract, usually involving unpaid notice, and the damages available.
- Settlement agreements: how negotiated exits are documented and the conditions that make them binding.
Termination of Employment: Getting the Exit Right
A well-handled termination of employment protects everyone involved. Employees should give notice in writing, keep copies of everything and check their final pay carefully. Employers should follow the contract, document each step, give clear written notice and pay exactly what is owed on time. Where the exit is disputed — or where a settlement agreement is on the table — early legal advice is almost always cheaper than a tribunal claim. Done properly, the end of employment is simply paperwork; done badly, it becomes litigation.
