Harriet PriceWhen Carlisle United confirmed on 28 May 2026 that Mark Hughes had left the club "by mutual agreement" following the National League playoff defeat, football fans immediately understood the subtext: the former Wales and Manchester City star's managerial tenure was over. But for the millions of UK workers who have received — or may one day receive — the same four words from their employer, the phrase raises urgent and often misunderstood questions about money, rights, and what happens next.
What does "left by mutual agreement" actually mean?
In employment law, a mutual agreement exit — also called a termination by consent — sits in a legal category quite different from a straightforward dismissal. Technically, both parties agree to end the contract. In practice, however, it is almost always the employer who initiates the conversation.
The key document that formalises such exits is a settlement agreement (formerly called a compromise agreement). Under section 203 of the Employment Rights Act 1996, a settlement agreement is the only mechanism by which an employee can legally waive statutory claims — such as unfair dismissal or wrongful dismissal — in exchange for a payment. Once signed, it is binding on both sides.
Crucially, the law requires that before you sign a settlement agreement, you must receive independent legal advice from a qualified solicitor, a certified trade union representative, or an ACAS-accredited conciliator. According to ACAS, a settlement agreement signed without that independent advice is not legally valid — meaning you could still pursue your employer at an employment tribunal even after signing.
Why do employers favour "mutual agreement" exits?
Employers prefer mutual exits for several reasons that have little to do with your interests. First, a settlement agreement effectively closes the door on future litigation. If you sign, you cannot later bring a claim for unfair dismissal, discrimination, or breach of contract — even if new evidence emerges.
Second, it avoids the reputational risk of a formal dismissal procedure. A performance management process, capability procedure, or redundancy round requires documentation, consultation periods, and appeals. A mutual exit bypasses all of that — which is precisely why ACAS warns that "settlement agreements can sometimes be used to resolve a dispute quickly and avoid the costs and uncertainty of an employment tribunal" on terms that suit the employer more than the employee.
Third, mutual exits often include confidentiality clauses — sometimes called non-disclosure agreements or NDAs — that prevent employees from speaking publicly about the terms or circumstances of their departure. This is standard in professional football management contracts and in senior corporate positions.
None of this means you should refuse such an offer. But it does mean you should understand it fully before agreeing to anything.
What are your rights when your employer approaches you?
If your employer proposes a mutual exit, you have several protections under UK law that kick in immediately.
The right to take time to consider. You cannot be pressured into signing immediately. ACAS guidelines recommend at least 10 calendar days to review any settlement agreement offer, and responsible employers follow this guidance.
The right to independent legal advice — paid for by the employer. Employers are legally required to make a financial contribution to the cost of your independent legal advice. The exact amount varies, but in 2026 the standard employer contribution ranges from £250 to £750 plus VAT. Your solicitor will tell you if this is inadequate for the complexity of your case.
The right to negotiate. An opening settlement offer is rarely the best offer. Employment lawyers routinely advise clients to counter-propose, particularly if the employee has additional claims (such as unpaid overtime, holiday pay, or discrimination) that the employer is keen to settle quietly.
The right to refuse and be protected. If you reject a settlement offer, your employer cannot simply dismiss you as a result. Settlement discussions are legally "without prejudice" and protected — they generally cannot be used as evidence in a tribunal unless both parties agree.
The £30,000 rule: how much of your settlement is tax-free?
This is where many employees are caught off guard. Under section 401 of the Income Tax (Earnings and Pensions) Act 2003, the first £30,000 of a genuine termination payment is exempt from both Income Tax and National Insurance contributions. Amounts above £30,000 are taxed at your marginal rate, and the employer also pays Class 1A National Insurance (currently 15%) on the excess.
However, not everything in a settlement agreement qualifies for the £30,000 exemption. The following elements are always fully taxable, regardless of how they appear in the document:
- Pay in lieu of notice (PILON)
- Unpaid wages or accrued holiday pay
- Contractual bonuses
- Garden leave payments
Only genuine compensation for loss of employment — not payments you were contractually due anyway — falls within the exemption. HMRC scrutinises settlement agreement documents closely, and if your employer labels a PILON payment as "compensation" to shelter it from tax, both you and your employer can face retrospective tax liability.
Concrete case: what a settlement might look like for a mid-level employee
Consider the situation of James, a 38-year-old regional operations manager at a logistics firm in Sheffield, earning £52,000 per year. On 3 August 2026, his line manager asked to meet "informally" and suggested the company would like him to "part ways by mutual agreement" after a restructuring. James has worked there for six years and has a four-month notice period in his contract.
Under UK law, James's minimum statutory entitlement would be:
- Statutory redundancy pay: 6 years × 1.5 weeks (over 22) at £700 weekly cap = approximately £5,250 (tax-free, within the £30,000 limit)
- PILON (4 months): £17,333 — fully taxable as earnings
- Accrued holiday: 12 days outstanding = £2,400 — fully taxable
The employer's initial offer was £28,000 as a global settlement. After James sought independent legal advice (his employer contributed £500 towards the solicitor's fee), his solicitor identified that he had a potential age discrimination angle related to the restructuring, and that a bonus of £3,200 had been promised verbally for Q2 2026 but never paid.
After negotiation, the final settlement reached £38,500. Of that, £30,000 qualified for the tax-free exemption; the remaining £8,500 was taxable. Net, James received approximately £34,000 after tax — compared to a take-home of around £21,500 had he simply accepted the original offer without advice.
The entire process, from initial approach to signed agreement, took 17 days. James had been unaware that he could negotiate, or that the verbal bonus was likely enforceable.
When should you involve an employment lawyer immediately?
Not every mutual exit requires intensive legal support — but certain situations warrant urgent advice:
- Your employer is proposing a very short deadline to sign (under 10 days)
- You believe the exit is linked to a protected characteristic (age, disability, pregnancy, race, religion, sex, sexual orientation)
- You have unclaimed bonuses, commissions, or share options in your contract
- You are being asked to sign a very broad NDA that restricts future employment
- Your employer is offering a payment substantially below your notice entitlement
If any of these apply, an experienced employment solicitor can make a material financial difference to your outcome — as the Carlisle United case illustrates, even an exit framed as amicable can involve significant financial negotiation behind the scenes.

For further guidance on employment law and settlement agreements, speaking with a specialist is the most effective first step. On Expert Zoom, you can find more on what happens when employment contracts expire or are renegotiated — a related issue that often arises alongside mutual exit discussions.
Employment situations like James's are more common than most workers realise. The difference between accepting an initial offer and seeking professional advice can run to thousands of pounds — and a qualified employment lawyer can help you understand exactly what you are signing away before you commit to anything.
