The Government is fundamentally reshaping how workplace disputes are resolved in Britain, with the ACAS Early Conciliation period set to double from six to twelve weeks from December 2025 – a change that will affect every employment relationship across the country and could significantly reduce the burden on already stretched employment tribunals.
Early Conciliation, a mandatory process introduced in 2014, requires individuals to contact ACAS (Advisory, Conciliation and Arbitration Service) before they can lodge a claim with an employment tribunal. In practice, this means any worker considering legal action – whether over unfair dismissal, discrimination, or unpaid wages – must first attempt to resolve their dispute through this impartial mediation service. The current six-week period was designed to offer a window for negotiation and settlement, with ACAS conciliators acting as neutral facilitators between employer and employee.
The decision to extend this period to twelve weeks, taking effect on 1 December 2025, reflects the Government's broader strategy to enhance out-of-court settlements and reduce pressure on the employment tribunal system. Proponents argue that six weeks often proves insufficient, particularly for complex cases involving discrimination claims or disputes with multiple parties. The extended timeframe could allow for more thorough discussions, deeper exploration of the issues, and ultimately a higher chance of reaching mutually agreeable resolutions without costly tribunal intervention.
For employers, this extension creates a double-edged sword. Whilst it provides more time to resolve disputes amicably – potentially avoiding the reputational damage and legal costs of tribunal proceedings – it also extends the pre-tribunal phase, creating prolonged periods of uncertainty. Businesses will need to review their internal dispute resolution procedures and ensure managers are properly trained to engage effectively throughout these longer conciliation periods, with resources potentially tied up for nearly three months per case.
Employees stand to benefit from the additional time to consider settlement offers and allow ACAS mediators to facilitate meaningful discussions. This could lead to a significant reduction in claims proceeding to full tribunal hearings, easing pressure on a system that has struggled with lengthy delays and potentially delivering fairer outcomes for workers who might otherwise have felt rushed into inadequate settlements under the current six-week deadline.
