The Employment Rights Act 2025 is not a single change arriving on a single date. Its measures are being introduced in stages, which means employers need a controlled programme of preparation rather than one large policy rewrite.

For most organisations, the immediate risk is not a missing paragraph in a handbook. It is the gap between written policy and the everyday decisions managers make about absence, probation, performance, family leave and dismissal.

Start with what has already changed

Several measures took effect in April 2026, including changes to Statutory Sick Pay, day-one paternity leave and unpaid parental leave, stronger whistleblowing protection in relation to sexual harassment, and a higher maximum protective award for failures in collective redundancy consultation.

That makes the first question simple: are your current documents, payroll processes and manager guidance already aligned?

Check the live versions of your sickness, family-leave, whistleblowing and redundancy materials. Look beyond the handbook. Template letters, intranet pages, payroll instructions and induction material often contain old wording long after a main policy has been updated.

Days 1–30: map decisions and owners

Create a short implementation register. For each relevant change, record:

  • what is changing and when;
  • which policy, process or template it affects;
  • who owns the update;
  • which managers make decisions in that area;
  • what training or communication is needed; and
  • where evidence of completion will be kept.

Prioritise frequent, high-consequence decisions. Absence management, probation, capability and dismissal deserve early attention because small inconsistencies can quickly become employee-relations problems.

Days 31–60: test manager confidence

From 1 January 2027, the qualifying period for ordinary unfair-dismissal protection is scheduled to reduce from two years to six months for relevant dismissals. The practical implication is not that managers should become more defensive. It is that early-employment decisions need to be better evidenced and more consistent.

Ask managers how they currently handle a new employee who is not meeting expectations. Do they set clear standards? Record the support offered? Address concerns promptly? Allow the employee to respond? Escalate consistently?

A short scenario-based session is usually more useful than circulating a long legal update. Give managers realistic examples and a clear route for seeking HR support before a decision is made.

Days 61–90: run a consistency check

Sample a small number of recent cases across different teams. You are looking for patterns, not blame:

  • Are similar issues handled in similar ways?
  • Can the reason for each decision be understood from the record?
  • Were expectations explained before consequences followed?
  • Was the employee given an opportunity to respond?
  • Were adjustments, protected characteristics or family-leave issues identified and considered?

Use the findings to refine templates and manager guidance. A policy becomes useful only when it improves the quality of a real decision.

Keep the plan live

Further measures are expected through late 2026 and 2027. The government’s published timetable states that future dates remain subject to parliamentary processes and may change. Assign one person to monitor official updates and review the implementation register monthly.

The strongest first step is not to predict every final detail. It is to build a reliable way of receiving changes, translating them into practice and checking that managers can apply them fairly.
