Employers are being advised to reassess the length of probationary periods in light of recent amendments to the Employment Rights Act 2025, which have significantly altered the framework governing unfair dismissal claims. The changes, effective from July 1, reduce the qualifying period for employees to bring unfair dismissal claims from two years of continuous service to six months.

This modification means that employees who began their employment on or after July 1 now gain protection against unfair dismissal much earlier than before. Previously, employers had a two-year window to assess new staff before they could be subject to such claims. The shortened qualifying period places increased pressure on organizations to thoroughly evaluate employee performance within the initial months of employment or adjust probationary terms accordingly.

Legal experts have emphasized the practical implications of these reforms. Louise Thawley, a partner at Mishcon de Reya, noted that the removal of the cap on unfair dismissal compensation, combined with the reduced qualifying period, presents heightened risks for employers, especially regarding high-earning staff. This could expose companies to substantial financial liabilities in dismissal cases, underscoring the importance of robust probationary frameworks.

Employers are encouraged to review current probation policies to ensure they provide sufficient time to assess the suitability of new hires, thereby mitigating the risk of unfair dismissal claims. The changes aim to strengthen employee protections, but they also require organizations to adapt their human resources practices to maintain compliance.

Overall, the reforms represent a significant shift in employment law, reflecting a move towards earlier protection for employees while challenging employers to balance fair evaluation processes with legal obligations.
