The Government has published a number of impact assessments and analytical documents relating to the measures in the Employment Rights Bill (‘the Bill’). The Employment Rights Bill economic analysis, published in October 2024, indicated that employment tribunal claims could increase by around 15% (representing around 4,750 claims) as a direct consequence of legislative changes. Most of this was accounted for by the proposals to make protection from unfair dismissal a “day one right”, the right to reasonable notice of shifts and the right to guaranteed hours. 

Since then a number of amendments have been made to the Bill (as outlined in Q1 of our March HR and Employment Law FAQS). Not all of these amendments were factored into the Government’s original impact assessment figure of around 15%. For example, the recent Extended Time Limit impact assessment suggests that the extension to the time limit which applies in relation to the issuing of tribunal claims - from three months to six months - could add around 1,750 additional employment tribunal claims into the system. Below, we explore the possible impact of the Bill in further detail.

A system already under strain

The employment tribunal service has faced considerable pressures for some time, with some Employment Tribunal Centres now listing long cases into 2028. Whilst there are regional variations on the speed at which tribunal hearings are allocated, tribunal administration at a national level tends to be slow, with frequent bottlenecks. Resourcing issues have long been a concern, and the reported cuts which the Government has indicated it will need to make moving forwards could exacerbate this.

Potential impact of the Bill

Various measures in the Bill could place further strain on the tribunal system. (As a reminder, we explored the contents of the original draft Bill in our earlier e-alert here.) In particular, employers should note the following:

  • Day one right to protection from unfair dismissal: Extension of protection from unfair dismissal is a key legislative change and this is expected to have the largest impact on the number of claims reaching tribunal. The Government’s impact assessment estimated an additional 3,350 ET1 cases of which 620 would require judicial time. Make UK’s Policy Team has encouraged the Government to focus on ensuring that the dismissal process during a new statutory probation period is as ‘light touch’ as possible, so that employers can dismiss during the statutory probation period (e.g. nine months) without the risk of incurring an unfair dismissal claim.
  • New right to reasonable notice of shifts: The impact assessment, which took into account that agency workers might also be given the right to reasonable notice of shifts, estimated an additional 850 ET1 cases of which 150 would require judicial time. In our view, clear guidance for employers on communication and how ‘reasonableness’ of notice provided would be assessed will be critical to ensuring compliance and reducing the risk of higher volumes of tribunal claims.
  • New right to guaranteed hours: The impact assessment, which also took into account the recent inclusion of agency workers, estimated an additional 300 ET1 cases of which 55 would require judicial time. Given the intricacies of the proposed provisions, we anticipate this new right could result in complex claims.
  • Additional powers for the Fair Work Agency (FWA) to bring tribunal claims on behalf of workers: This new power could lead to further pressure on the tribunal system. Whilst the FWA impact assessment indicates that introducing the FWA may reduce pressure on the tribunal system (by, for example, taking over enforcement of holiday pay), it is feasible that proposed new powers for the FWA to bring claims on a worker’s behalf when the worker has declined to do so could potentially undermine this goal.

What next?

There is no doubt that various proposals set out in the Bill risk placing even more pressure on an already struggling employment tribunal system. On the one hand, it is encouraging that the Government has shown willingness to consider some of employers’ concerns linked to tribunal capacity (shown by the Government’s decision, rightly, not to introduce interim relief in fire and rehire/collective redundancy cases). However, it is important that employers’ concerns are taken into account as other details about various measures in the Bill evolve over the coming months.

Make UK has urged the Government to continue to consider how amendments to the Bill and any consequential regulations will impact tribunal capacity. It will be useful to see whether the Government outlines as part of its forthcoming Spending Review how it will allocate resources to the tribunal system over the review period. It will also be important to ensure that Acas has sufficient resources to improve and expand early conciliation, to prevent a higher number of tribunal claims arising as a result of measures in the Bill.
