UK Employment Law for Expats: Contracts, Dismissal, Redundancy & the Day-One Rights Reform (2026)

British employment law is in its biggest overhaul in a generation — and expats are reading yesterday’s rules. The Employment Rights Act 2024’s reform package — day-one unfair-dismissal protection with a statutory probation regime, restrictions on fire-and-rehire, zero-hours reforms — is phasing in through 2026–27, layering onto a system already unlike anywhere else in this series: qualifying periods, tribunals without fees, and a redundancy culture with fixed statutory math but negotiated enhancements. This guide states the practical 2026 position for international employees and their employers: contracts and day-one statements, probation and notice, the dismissal framework old and new, redundancy, holiday and sick pay, family leave, covenants, and how tribunal claims actually run.

What must a UK employment contract contain — and what fills its gaps?

Every worker is entitled to a written statement of particulars on day one: pay, hours, holiday, notice, probation terms, benefits, training entitlements — the post-2020 expanded list. The contract is genuinely central (this is a common-law system), but statute floors it everywhere: minimum wage, working time, holiday, notice, and the discrimination regime cannot be contracted away.

Implied terms fill what the document misses — above all the mutual duty of trust and confidence, whose serious breach by the employer lets an employee resign and claim constructive dismissal. Custom and practice can harden repeated discretionary benefits (that ‘discretionary’ bonus paid identically for a decade) into entitlements.

Reading order for internationals: notice and PILON clause, probation terms, restrictive covenants and garden-leave provisions, bonus/commission wording (the word ‘discretionary’ is litigated constantly), and any repayment clauses for relocation or the visa costs from our UK visa guide — clawbacks of some sponsor-side charges are unlawful, and the lawful ones must be drafted as genuine pre-estimates rather than penalties.

How do probation, notice, and garden leave operate?

Probation in the UK has been contractual custom rather than statute — typically three to six months with shortened notice — but the reform package gives it legal architecture: a statutory ‘initial period’ (consulted at around nine months) during which a lighter-touch dismissal process applies even as unfair-dismissal rights move to day one. Until commencement dates pass for your case, the old two-year qualifying world governs; afterwards, process during probation stops being optional.

Notice stacks contract over statute (one week per year served, capped at twelve); senior contracts run three to twelve months, and employers choose between working the notice, PILON (immediate exit, taxed as earnings), and garden leave — employed, paid, excluded from work, and off the market: the UK’s favorite tool for protecting client relationships during transitions.

Resignation mechanics mirror it: your notice binds you, garden leave can be imposed if contracted, and walking early is technically breach — rarely sued, often remembered. For visa holders, notice interacts with the 60-day curtailment clock; sequence the resignation against the new CoS as the visa guide describes.

What makes a dismissal fair — and what changes under the reforms?

The framework: dismissal must fall within the five potentially fair reasons — capability, conduct, redundancy, statutory illegality (including right-to-work loss), or ‘some other substantial reason’ — and follow a fair process (investigation, hearing, appeal per the Acas Code, with uplifts of up to 25% on awards for Code breaches). Unfair dismissal compensation combines a basic award (redundancy-formula math) and a capped compensatory award.

Day-one claims have always existed regardless of tenure: discrimination under the Equality Act (nine protected characteristics, uncapped compensation), whistleblowing detriment and dismissal (uncapped), health-and-safety and assertion-of-statutory-rights dismissals — the claims that make ‘under two years, no rights’ always half-wrong.

The Employment Rights Act package extends ordinary unfair-dismissal protection to day one (with the statutory probation carve-down), restricts fire-and-rehire, and reforms collective redundancy triggers — commencement phased through 2026–27 with consultations setting the detail. Employers should already be running day-one-compliant processes; employees should check which regime their dismissal date falls under before accepting ‘you have no rights’ at face value.

How do redundancy and settlement agreements actually run?

A lawful redundancy needs a genuine redundancy situation, fair pooling and objective selection, meaningful consultation (individual always; collective consultation of 30/45 days when 20+/100+ redundancies at one establishment are proposed, with protective awards for failure), and consideration of alternative roles — with special protection ordering for those on family leave.

The money: statutory redundancy pay per the age-and-service formula (capped week’s pay, 20-year maximum) is the floor; enhanced schemes and negotiated exits sit above it, and the first £30,000 of genuine termination payments is income-tax-free (PILON and holiday pay are not — they are earnings).

Settlement agreements are the UK’s exit instrument: waiving claims requires the statutory formalities including independent legal advice the employer customarily funds — use that adviser properly, because the agreement is where notice, the £30k structuring, references, covenants, and — for sponsored workers — cooperation on the visa transition all get written down or lost.

Holiday, sick pay, and family leave — the entitlement stack

Holiday: 5.6 weeks statutory (28 days full-time, bank holidays includable), accruing from day one, payable at exit — with ‘normal remuneration’ case law pulling regular overtime and commission into holiday pay, and rolled-up holiday pay newly lawful for irregular-hours workers. Professional packages commonly add days above the floor.

Sick pay: statutory SSP is famously thin — a modest weekly flat rate for up to 28 weeks (with reforms removing waiting days and extending coverage phasing in) — which is why occupational sick pay in your contract is a real compensation term, not boilerplate; UK long-term-illness protection lives in employer schemes and income-protection insurance, not the Dutch-style statutory two years.

Family leave: 52 weeks’ maternity (39 paid — 90% for six weeks then the statutory flat rate), day-one paternity leave reforms, shared parental leave splitting the year between parents, adoption on maternity-equivalent terms, and the newer additions — carer’s leave, neonatal care leave, and flexible-working requests as a day-one right the employer must handle within the statutory framework.

Restrictive covenants, TUPE, and worker status — the structural doctrines

Covenants (non-compete, non-solicit, non-deal) are void as restraints of trade unless reasonable in protecting legitimate interests — tightly drafted in time (3–12 months is the enforced range), scope, and geography, with garden leave offsetting duration. Courts sever what they can and refuse what overreaches; injunctions are real here, unlike the US damages-first culture, and government proposals to cap non-compete length have floated without landing — verify status if it matters.

TUPE transfers employees automatically with the business or service that employs them — same terms, continuity preserved, dismissals connected to the transfer unfair, and information/consultation duties on both sides. Outsourcing-heavy sectors run on it; expats acquired with a business should know their contract crossed intact.

Worker status is the third rail: the employee/worker/self-employed triage (with ‘workers’ getting holiday, minimum wage, and pension auto-enrolment) has produced the gig-economy case law, and IR35’s off-payroll rules make medium/large clients responsible for judging contractors’ status — the employer-side machinery in our UK compliance guide. If you contract through a personal service company, that guide’s IR35 section is your rulebook too.

How do tribunal claims work — and what should an expat document?

Employment tribunals charge no fees, sit less formally than courts, and require Acas early conciliation before claims — a free negotiation window that settles a large share of disputes. Remedies: unfair dismissal’s capped compensatory award, uncapped discrimination and whistleblowing awards, and reinstatement in theory. Costs rarely shift, so each side bears its own — which shapes settlement economics on both sides.

The evidentiary culture matches the rest of this series: contemporaneous documents win. Keep offer letters, particulars, appraisals, the handbook version in force, and a dated log; raise grievances in writing through internal procedure first (tribunals expect it, and the Acas Code uplift/downlift enforces it).

For sponsored workers, add the immigration overlay: dismissal triggers the sponsor’s reporting duties and your 60-day clock, but immigration status is irrelevant to your employment rights — tribunals hear visa holders’ claims like anyone’s, and ‘they’ll just report me’ retaliation around protected complaints is itself actionable. The two systems run in parallel; manage both calendars, as the relocation guide‘s exit section also reminds.
