Summary
October 2026 reforms will force UK employers to take “all reasonable steps” to prevent workplace sexual harassment and create a new standalone claim for third-party harassment after a single incident.
That tougher standard raises exposure because harassment awards can already be lifted by 25%, while employers may also face enforcement action and will need updated risk assessments, policies, reporting procedures and training.
Trade union changes arriving in August and October 2026 include electronic balloting, mandatory notices telling workers of their right to join a union, and a broad right for unions to seek physical and digital workplace access.
The access regime could hit repeat non-compliance with fines of up to £500,000, with only limited exceptions such as micro-employers with fewer than 21 staff.
The Act also plans to double most employment tribunal filing limits to 6 months from 3, with further January 2027 reforms set to cut unfair-dismissal qualifying service to 6 months from 2 years.
Will stronger harassment laws finally protect frontline staff, or just create more legal hurdles for employers?
With uncapped dismissal awards and massive fines, are UK businesses facing an unavoidable surge in litigation risk?
How will new access rights empower unions to organize workers in today's remote and hybrid workplaces?

Overview
The UK Employment Rights Act 2025 is a landmark reform that will reshape workplace rights and responsibilities across the nation. Rolled out in phases from December 2025 through 2027, with major changes in October 2026, the Act aims to address long-standing workplace imbalances. Its core goals are to provide greater job security for workers and deter exploitative practices by rogue employers.
