Five Employment Reforms Landing in 2026 — and a 90-Day Plan for Firms Without an HR Team

Very few people run a business because they enjoy employment law. Yet by the end of April 2026, a typical forty-person company will need to have rewritten its sickness policy, refreshed its family leave paperwork, reviewed its rota practices and, in many cases, reissued contracts of employment. Each change is manageable on its own. Taken together — and sitting alongside a new enforcement body with real powers — they reward the firms that prepare early and penalise the ones that do not.

What follows is a working checklist rather than a legal treatise. Commencement is staggered and precise dates are set by regulation, so the timetable below should be confirmed against the latest government guidance before any policy is signed off.

Why 2026 is different

Since the 1990s, employment law has tended to arrive in modest increments that a competent office manager could absorb. The 2025 Employment Rights Act broke that pattern. Its provisions are being switched on in phases, and 2026 is the year when several of the higher-traffic provisions reach small and medium-sized employers at the same time.

The pattern matters more than any single item. Reforms that were designed with large employers in mind — neonatal leave, guaranteed hours, statutory sick pay from day one — depend on payroll configuration, rota data and line manager behaviour. That is precisely where a business without an HR function is thinnest.

The five changes most likely to catch an SME out

1. Statutory sick pay loses its waiting days

From April 2026, statutory sick pay becomes payable from the first qualifying day of sickness rather than the fourth, and the lower earnings limit is removed. In practice, the lowest-paid and part-time staff — heavily represented in manufacturing, hospitality, care and logistics — become eligible for the first time.

Absence stops being a mild administrative nuisance and becomes a payroll event from day one. Update absence triggers, brief supervisors on fit notes and self-certification, and model the cost against last year's absence data. Check, too, whether you still qualify for small employer recovery of statutory sick pay above the statutory threshold; the arithmetic has changed for a number of firms.

2. Neonatal care leave arrives with day-one status

Parents whose baby requires neonatal care will be entitled to up to twelve weeks' additional leave and pay, on top of maternity and paternity entitlements, and from the first day of employment. Few SMEs will use it often. On the one occasion it is needed, it will be needed badly, and a manager improvising a response is the worst possible outcome. Add the entitlement to the family leave policy, brief the payroll provider and make clear that it is a statutory right, not a discretionary kindness.

3. Paternity leave becomes splittable

Fathers and partners will be able to take their two weeks in non-consecutive blocks, with a shorter notice period. The policy wording is the easy part; rota planning is where this bites. A production line that assumes both weeks are taken together will find itself short-staffed with a week's warning.

4. Guaranteed hours for regular casuals

Workers on zero or low-hours contracts who work regular hours across a reference period will have a right to be offered guaranteed hours reflecting that pattern, together with compensation where shifts are cancelled at short notice. The reference period looks backwards, so the evidence you will need is the rota data you already hold. Audit it now rather than reconstruct it under pressure.

5. Fire and rehire moves from poor practice to prohibited

Dismissal for refusing a contract variation will be treated as automatically unfair where the employer could reasonably have avoided the change, with a higher compensation uplift. If any part of your cost base depends on renegotiating terms after the fact — overtime rates, shift allowances, Sunday premiums — that assumption needs revisiting this year, not next.

The quiet sixth change: enforcement

A single enforcement body now has powers to inspect, fine and recover arrears without an employment tribunal claim. Record-keeping has moved from housekeeping to risk management. Contracts, payslips, holiday calculations and working time records should all be capable of surviving a request for documents at short notice.

A 90-day action plan

Days 1 to 30 — audit. Pull together every contract, the staff handbook, absence data for the past two years and rota records for the past six months. Identify who is on zero or low-hours terms and how regular their pattern actually is. Circulate a one-page summary to the board: what changes, who it affects, what it costs.

Days 31 to 60 — draft and train. Reissue contracts, update the handbook and rewrite the sickness and family leave policies. Then train line managers, because policies fail at the supervisor level, not the policy level. Two hours with the people who approve absence and set rotas is worth more than ten pages of elegant wording.

Days 61 to 90 — embed. Put a compliance calendar in the diary, with a named owner for each date. Introduce a simple sign-off for probation decisions and dismissals so that no manager acts alone. Record the reasoning behind decisions as they are made; contemporaneous notes are the difference between a defensible position and an expensive one.

Case study: a forty-person packaging business

A West Yorkshire packaging manufacturer, family-owned since 1986 and now employing forty people, began its review in January 2026 with what its managing director described as “a filing cabinet and a certain amount of optimism”. Twelve staff were on flexible or low-hours arrangements, the handbook had last been issued in 2016, and statutory sick pay was administered by a bookkeeper working one day a week.

The audit took three weeks and produced two uncomfortable findings: the rota data showed several casual staff working patterns indistinguishable from full-time hours, and modelling the new sick pay rules added roughly £9,000 a year to the absence budget at historical absence rates. Contracts were reissued in February, the handbook was rewritten in March, and supervisors were trained in a single morning session.

The finance director's summary is worth repeating: the money was not the difficulty. The difficulty was discovering how much of the firm's practice lived in people's heads. By April the company had a compliance calendar, a named owner for each obligation and a board paper that took ten minutes to read.

Where counsel earns its keep

Most of this work is administrative, and much of it can be done in-house. The value of taking advice lies in the handful of judgement calls: whether a particular working pattern triggers guaranteed hours, how to restructure an allowance without creating a dismissal risk, and what to do about a long-standing arrangement that nobody has ever written down.

Those questions are cheaper to answer in February than in a tribunal hearing in November.
