The Employment Rights Act 2025: Preparing for change

The Employment Rights Act 2025 (ERA) represents the most significant overhaul of UK employment law in a generation. Its overall impact is to rebalance risk and flexibility in favour of workers, materially increasing employer financial exposure, compliance obligations and litigation risk. The changes will be phased in during 2026–2027.

Unfair dismissal: Earlier access to rights, significantly higher risk and financial exposure

What changes?

  • The qualifying period for ordinary unfair dismissal will reduce from two years to six months (expected 1 January 2027).
  • The statutory caps on compensatory awards for unfair dismissal will be removed entirely.

Impact:

  • A substantial expansion of the protected workforce (estimated at over 6 million additional employees).
  • Much greater financial exposure in dismissal claims, particularly for higher earners and those with poor re‑employment prospects.
  • Increased pressure on probation management, documentation and early‑stage performance handling.
  • Expected increase in tribunal activity, with knock‑on effects for dispute resolution strategy.

Day‑one and expanded family & sickness rights

What changes (from April 2026)?

  • Statutory Sick Pay (SSP) payable from day one, with the Lower Earnings Limit removed.
  • Day‑one rights to paternity leave and unpaid parental leave.
  • New and extended bereavement leave, including for early pregnancy loss.

Impact:

  • Increased cost and administrative burden, particularly for lower‑paid and short‑service workforces.
  • Need to update contracts, policies and payroll systems.
  • Greater risk of discrimination and detriment claims linked to absence and leave handling.

Zero‑ and low‑hours work: Reduced flexibility for employers

What changes (largely from 2027, subject to regulations)?

  • New rights for qualifying workers to:
    • Guaranteed hours contracts reflecting actual working patterns.
    • Advance notice of shifts.
    • Compensation for cancelled or curtailed shifts.

Impact:

  • A fundamental shift away from ‘one‑sided flexibility’.
  • Increased cost certainty for workers, but reduced operational agility for employers particularly in sectors such as hospitality, retail and social care.
  • Likely need for workforce model redesign and closer monitoring of working patterns.

Collective redundancies: Higher stakes and wider triggers

What changes?

  • The maximum protective award for failure to consult will double from 90 to 180 days’ pay (April 2026).
  • A  new organisation‑wide redundancy trigger is proposed (details subject to consultation and regulations).

Impact:

  • Significantly increased financial exposure in collective redundancy consultation failures.
  • Greater complexity for large or multi‑site employers, particularly during restructures.
  • Heightened importance of early legal input and consultation planning.

Fire and rehire: Stronger statutory restrictions

What changes?

  • ERA introduces statutory limits on ‘fire and rehire’ practices, with dismissals potentially becoming automatically unfair where statutory conditions are not met (expected Jan 2027).

Impact:

  • Employers will face narrower scope to impose contractual change through dismissal.
  • Greater reliance on collective consultation, incentives and negotiated variation.
  • Increased litigation risk where business change is poorly evidenced.

Harassment, non-disclosure agreements and whistleblowing

What changes?

  • Employers must take ‘all reasonable steps’ to prevent sexual harassment, including by third parties.
  • NDAs preventing disclosure of harassment or discrimination will be void (with limited exceptions).
  • Complaints of sexual harassment become qualifying disclosures for whistleblowing protection.

       Impact:

  • Higher expectations around training, culture and preventative measures.
  • Reduced utility of NDAs in resolving disputes.
  • Increased risk of uncapped whistleblowing detriment claims.

Trade unions and industrial action

What changes?

  • Repeal of much of the Trade Union Act 2016.
  • Simplified balloting, longer mandates and enhanced protections against dismissal for industrial action.

Impact:

  • Lower barriers to lawful industrial action.
  • Stronger union leverage in negotiations, particularly in unionised or public‑facing sectors.

Enforcement: A shift towards proactive regulation

What changes?

  • Creation of a new Fair Work Agency, consolidating enforcement of rights such as minimum wage, SSP and holiday pay.

Impact:

  • Greater likelihood of proactive enforcement, not just individual claims.
  • Increased importance of compliance audits and governance.

Overall impact – Key takeaways

  • The ERA significantly increases employer legal and financial risk, particularly around dismissals and restructuring.
  • It front‑loads employment protection, reducing the value of short service as a risk buffer.
  • Many of the most consequential changes depend on secondary legislation, meaning uncertainty remains through 2026.
  • For employers, the ERA shifts the focus from reactive defence to preventative HR and legal strategy.
