The Employment Rights Act 2025 has moved firmly into its implementation phase. Important reforms are already in force, further changes have confirmed commencement dates, and some of the Act’s most complex provisions still depend on regulations and consultation.
For employers and their advisers, the challenge is no longer simply identifying the Act’s headline reforms. It is understanding what applies now, what is changing next and what organisations should be doing to prepare.
Lex HR has published The Employment Rights Act 2025: A Practitioner’s Guide, providing detailed legal analysis and practical implementation guidance for employment lawyers, HR professionals, in-house legal teams and HR consultants.
A phased programme of employment law reform
Several significant reforms took effect in April 2026, including changes to Statutory Sick Pay, day-one paternity and unpaid parental leave, the collective redundancy protective award and whistleblowing protection relating to sexual harassment.
Electronic and workplace balloting for statutory trade union ballots took effect on 25 August 2026. Further changes will follow, including:
The extension of most employment tribunal time limits from three to six months from 1 October 2026
Strengthened duties relating to sexual harassment and third-party harassment from 30 October 2026
A six-month qualifying period for ordinary unfair dismissal, together with the removal of the statutory compensatory award cap, for dismissals from 1 January 2027
New restrictions on dismissal and re-engagement from January 2027
Further reforms during 2027 covering guaranteed hours, shift notice, collective redundancy consultation, flexible working and family-related rights
Some of these provisions are settled. Others require secondary legislation to determine precisely how they will operate. The government’s implementation timetable also makes clear that future dates remain subject to parliamentary processes.
What the report covers
The report examines the principal reforms introduced by the Act, including:
The new six-month qualifying period for ordinary unfair dismissal
Contractual probation and dismissal risk
Guaranteed hours, zero-hours contracts and shift rights
Sexual harassment prevention and third-party harassment
Collective redundancy consultation and protective awards
Dismissal and re-engagement
Trade union rights and workplace access
Family-related leave and flexible working
Statutory Sick Pay reform
Whistleblowing and confidentiality provisions
Employment contracts, policies and implementation planning
Each chapter distinguishes the current legal position from future reforms and identifies matters that remain dependent on regulations. Detailed analysis is supported by practical scenarios, risk considerations and recommended actions.
From legal analysis to practical implementation
The report is designed to help readers move beyond a summary of the legislation and consider what the reforms mean operationally.
It addresses the policies, contracts, procedures, recordkeeping and management practices that organisations may need to review. It also considers how employers can prepare without treating consultation proposals or unresolved regulatory details as settled law.
The result is a working guide for advising clients, briefing senior management, assessing organisational exposure and building an implementation programme around the Act’s phased commencement.
Research and editorial approach
The report was produced by the Lex HR editorial team, drawing on primary legal sources and Lex HR’s curated employment-law knowledge base.
