The Employment Rights Act 2025 received Royal Assent on 18 December 2025, marking a pivotal moment in UK employment legislation.

Widely regarded as the most significant upgrade to workers’ rights in a generation, the Act introduces 28 wide ranging reforms that will reshape the employment landscape for years to come. From a new unfair dismissal regime and guaranteed hours for casual workers, to enhanced trade union access and new liabilities for workplace harassment, the Employment Rights Act signals a decisive shift in how employers engage with their workforce.

While implementation will be phased, the first wave of changes in February 2026 is particularly relevant for unionised businesses. These include streamlined procedures for calling industrial action, and greater protections for employees taking part in such action. Further waves of changes will follow in April and October, as well as a myriad of consultations on proposals which may stretch into 2027.
