Amelia DaviesOn 22 May 2026, Manchester United confirmed Michael Carrick as their permanent head coach on a two-year deal running to 2028, ending four months of interim status following Ruben Amorim's dismissal in January. Carrick guided the club to 11 wins from 16 matches, secured third place in the Premier League, and returned United to the Champions League — all before a permanent contract was offered. His journey from interim to permanent mirrors a legal transition millions of UK workers navigate each year, with rights, protections, and entitlements that many people do not realise they already possess.
Interim Roles Are Now a Feature of UK Working Life
The interim and fixed-term employment market has expanded significantly across the UK. In sectors from financial services to healthcare to senior management, organisations routinely fill gaps with temporary appointments — and then, when results prove themselves, convert those appointments to permanent roles.
Football clubs are a compressed version of this reality. A head coach is sacked mid-season. The club installs a trusted figure on a short-term deal. Results follow. The board votes to make the arrangement permanent. Carrick's trajectory — interim appointment on 13 January 2026, permanent contract announced 22 May 2026 — played out in public, but the underlying employment question is one that plays out privately in thousands of UK workplaces each year.
What changes legally at the moment of conversion is not always well understood, even by the workers involved. In many cases, the legal change is less about gaining new rights and more about understanding which rights already existed from day one.
The Core Legal Principle: Continuity of Employment Does Not Reset
Under the Employment Rights Act 1996, continuity of employment begins from the first day a worker starts work — not from the date their role is reclassified as permanent. This is the central point that employment solicitors emphasise when advising workers on interim-to-permanent transitions.
Unfair dismissal protection, one of the most significant employment rights available in England and Wales, attaches after two years of continuous employment. A worker who spent eight months on a fixed-term contract before being converted to permanent status enters their new permanent role with eight months already counted toward that threshold. The employer cannot reset the clock, and any contractual wording that attempts to do so is likely unenforceable.
The same principle applies to statutory redundancy pay. The calculation formula depends on length of service: half a week's gross pay per year of service under 22, one week's pay per year between 22 and 41, one and a half weeks' pay per year over 41. The starting date for that calculation is the first day of continuous employment — which, for most converted interim workers, is the date they joined on a fixed-term basis.
Fixed-term workers also hold protections under the Fixed-Term Employees (Prevention of Less Favourable Treatment) Regulations 2002. Employers cannot treat fixed-term employees less favourably than comparable permanent colleagues on objective grounds unless there is a proportionate reason. This means that access to pension enrolment, performance bonuses, healthcare schemes, or other benefits must be extended to interim workers on the same basis as permanent staff — unless the employer can demonstrate a clear justification for the difference. A permanent contract offer does not retroactively excuse less favourable treatment during the interim phase.
A Concrete Scenario: What a Senior Interim Manager Stands to Gain
Consider the situation of Emma, a 41-year-old operations director hired on a six-month fixed-term contract at a manufacturing firm, earning £108,000 per year. After five months, the company offers her a permanent role at £118,000.
Before Emma signs the permanent contract, several legal points require attention:
Continuous service wording. The offer letter and contract should confirm that her employment began on the first day of her interim engagement, not on the date of conversion. If the contract states that employment "commences" on the conversion date, that clause may attempt to strip Emma of five months of accrued service. In law, the clause would likely fail — but it creates confusion and litigation risk.
Redundancy exposure. If Emma were made redundant 15 months after being converted to permanent status, she would have 20 months of continuous service (5 interim + 15 permanent). At one week's pay per year of service (she is between 22 and 41), and with the statutory weekly cap applied, she would receive a redundancy payment calculated on the full 20 months. Had the contract successfully backdated her start date to the conversion date, that payment would be calculated on 15 months only — a meaningful difference at her salary level.
Probationary clauses. Some employers introduce a probationary period into the permanent contract — typically three to six months. This does not reset employment rights. Emma's unfair dismissal protection still accumulates from her original start date. A probationary period in a permanent contract limits notice periods and review processes; it does not alter statutory continuity of employment.
New restrictive covenants. Many permanent contracts introduce obligations that were absent from the interim arrangement: garden leave provisions, post-termination non-compete clauses, non-solicitation restrictions on clients or colleagues. These are new contractual obligations, and Emma has every right to negotiate them before signing. A non-compete clause that prevents her from working in the same sector for 12 months may be enforceable; a clause spanning three years or covering an unreasonably wide geographic area almost certainly would not be upheld by a tribunal.
At £118,000, the financial stakes of signing a poorly-drafted permanent contract are considerable. An employment solicitor can review a conversion offer, identify problematic clauses, and confirm continuity of service in a single consultation — work that takes a few hours and can prevent years of legal uncertainty.
What Every Interim Worker Should Check Before Converting
Employment specialists recommend four specific checks before an interim worker signs a permanent contract:
1. Start date confirmation. The permanent contract should explicitly record the original interim start date as the commencement of continuous employment.
2. Accrued holiday carryover. Any unused statutory holiday built up during the interim period must be carried forward or paid out. The conversion is not a termination; the holiday entitlement does not reset.
3. Benefit parity review. Any benefits not extended during the interim phase — pension contributions above the auto-enrolment minimum, share options, private medical insurance — should now be addressed. The employer should either offer them or provide a documented reason for continued exclusion.
4. New clause scrutiny. Post-termination restrictions, intellectual property assignments, and confidentiality obligations may appear for the first time in the permanent offer. Each one deserves independent legal review before the contract is signed.
For workers in football or any other sector, the lesson from Carrick's transition is that the interim phase is not a legal blank. As GOV.UK guidance on fixed-term contracts makes clear, the protections available to fixed-term employees are substantial — and they carry through into any permanent arrangement that follows. Understanding them before conversion is the point at which a legal consultation pays for itself many times over.
