Six-month tribunal time limits: the case for a 180-day people-risk system

A longer clock changes the management task, not the test for liability

The extension of most Employment Tribunal (ET) limitation periods from three months to six months, due to take effect on 1 October 2026, should be read as a management-capability reform as much as a procedural one. It gives workers more time to seek advice, assess an employer’s response and decide whether to take formal steps. It also extends the period in which an unresolved grievance, poorly evidenced decision or deteriorating working relationship can become a material business risk.

The transition is more nuanced than a blanket six-month rule. The government’s implementation timetable states that the new limits generally apply where the relevant act or omission took place on or after 1 October 2026. Claim type, jurisdiction and the facts of an alleged continuing act may therefore remain important. A separate change concerning the limitation period for breach-of-contract claims in Scotland is scheduled for 9 November 2026. (GOV.UK, 2026) ↗; (The Employment Rights Act 2025 (Commencement No. 5 and Transitional Provisions) (Amendment) Regulations 2026, 2026) ↗

That matters because the reform does not make ordinary disagreement unlawful, guarantee that a complaint will become a claim, or remove the value of prompt resolution. It changes the practical life of a dispute. A business may now need to reconstruct a contested decision much later, when the manager has left, a rota has been overwritten or key communications sit across personal inboxes, messaging platforms and scheduling software.

For smaller employers, this is chiefly an organisational-memory problem. A performance concern, flexible-working request, pay dispute or conduct issue may be handled informally by a line manager who has sound reasons but records none of them. If the relationship later breaks down, the business is left trying to explain a reasonable decision without a reliable chronology or evidence trail. The commercial exposure is not confined to legal cost: leadership time, shift cover, absence, customer service and retention can all be affected.

Sanctuary’s interpretation is that the right response is disciplined management rather than litigation theatre. Managers should be able to show what concern was raised, what evidence they checked, who made the decision, why the outcome was reasonable at the time and how the individual had a meaningful chance to respond. That is a higher standard than informal recollection, but it need not turn every difficult conversation into a lawyer-led event.

The evidence supports earlier resolution, but not simplistic claims about settlement

Acas data shows that employment conflict has a substantial middle ground between informal closure and a full Tribunal hearing. Of early-conciliation notifications received between October and December 2025, 68% did not progress to an ET1 claim. This group included 3,624 Acas settlements and 24,699 cases in which an ET1 was avoided. In the subsequent January to March 2026 period, 80% of Tribunal cases reaching an outcome did not proceed to a hearing; Acas settlements represented around 69% of the cases that did not reach one. (Acas, 2026) ↗

These figures should be read carefully. They do not demonstrate that settlement is always fair or desirable, nor that any specific employer intervention causes a dispute to resolve. They also pre-date the October 2026 change, so they cannot evidence its future effect. Their value is narrower and more useful: a full hearing is not the standard endpoint of an employment dispute, and the quality of handling before that point has practical importance.

A six-month window could make constructive internal resolution more valuable. A worker may have more time to test whether a concern has been properly investigated rather than acting chiefly to preserve a short deadline. An employer may have more time to correct an error, obtain missing evidence or repair a working relationship. But those benefits are contingent. Additional time improves outcomes only when it is used to make a better decision; it becomes harmful when it licenses drift.

The mechanism is straightforward. Delay weakens both evidence and trust. Recollections become less reliable, schedules and messages may be lost, and a succession of vague holding responses can make an internal process appear performative. Conversely, rushed decisions can suppress relevant facts and create the impression that the outcome was predetermined. The practical objective is therefore neither speed at all costs nor exhaustive process for every concern. It is timely, intelligible and proportionate handling.

This distinction is particularly important for high-street businesses, growing firms and owner-managed employers. In these settings, prolonged conflict often first appears as operational friction: rota instability, lower manager confidence, sickness absence or avoidable turnover. A credible response process is therefore part of management infrastructure, not merely a litigation defence.

Tribunal data raises the stakes, while limiting what can be predicted

The Tribunal context strengthens the argument for capable internal management, but it does not justify alarmist forecasts. In 2025/26, Employment Tribunals received 50,000 single-claim receipts and disposed of 26,000. The open single-claim caseload was 64,000 at the end of March 2026, 55% higher than at the end of 2024/25. However, the Ministry of Justice cautions that comparison is affected by the phased introduction of a reformed case-management system. The data is therefore not a clean measure of worsening Tribunal performance. (GOV.UK, 2026) ↗

The timing also sets a clear evidential boundary. A reform commencing in October 2026 cannot explain March 2026 caseload figures, and it is too early to claim that longer limitation periods will either overwhelm the Tribunal system or materially increase claims. Post-reform cohorts will take time to enter the process and reach outcomes.

A more defensible conclusion is that formal proceedings are seldom a quick operational answer to a damaged employment relationship. Whether or not a case reaches hearing, prolonged uncertainty absorbs management capacity and can make ordinary workforce decisions harder. This burden is often disproportionate for SMEs, where the same person may be responsible for service delivery, staffing and commercial growth.

There is a genuine trade-off in the response. Centralising every difficult discussion in HR or external legal advice can reduce inconsistency, but may delay correction and discourage line managers from having fair, direct conversations. Leaving managers unsupported produces the opposite failure: improvised decisions, inconsistent treatment and inadequate records.

Sanctuary recommends controlled decentralisation. Line managers should be equipped to address routine matters early, with clear escalation triggers for serious allegations, repeated concerns, acute power imbalances, suspected retaliation, significant health or safety issues, legal complexity, or decisions that may end employment. This approach treats management capability as productive infrastructure: it reduces avoidable rework, supports retention and lessens dependence on informal memory as an organisation grows.

A proportionate 180-day system for material people issues

The following is a management operating model, not a legal limitation period or a substitute for case-specific advice. Its purpose is to maintain decision quality during the period in which a material workplace issue may remain live. It should not be imposed mechanically on every disagreement.

First, introduce a seven-day triage discipline for matters that could materially affect pay, performance, conduct, health, equality, working time, role security or the employment relationship. Record the concern, identify immediate welfare or safety needs, preserve relevant evidence and assign a decision owner. Triage is not a finding of fault; it is protection against evidence loss and organisational drift.

Second, aim for a 28-day fact-and-response standard where an issue can properly be handled internally. The employee should understand the issue being considered, have a genuine opportunity to give their account and receive either a reasoned outcome or a clear explanation of what remains unresolved. Decision-makers should distinguish contemporaneous records from later recollection, and established facts from assumptions.

Third, require a 90-day assurance review for unresolved material cases. A senior manager, HR lead or appropriate adviser should test whether the case is drifting: are relevant records missing; have deadlines moved repeatedly; is treatment consistent; have adjustments or interim protections been considered; and has the employment relationship deteriorated? The answer may point towards a formal investigation, facilitated discussion, occupational-health input, mediation or engagement with Acas early conciliation.

Fourth, maintain a secure 180-day case record for significant matters. It should include the original concern, chronology, evidence considered, meeting notes, material communications, decisions, remedies or adjustments offered, and the rationale for closure or escalation. This is not an argument for indiscriminate retention: information should be necessary, securely held and accessible only to people with a legitimate role.

The value lies in sequencing. The model turns the vague instruction to deal with matters early into identifiable points of ownership, response, review and evidence preservation. It can also reveal patterns that single-case handling conceals, such as recurring rota disputes, repeated complaints about one manager or a persistent failure to consider adjustments.

Measure resolution quality, not merely closure

A faster system can create fresh risk when it is designed mainly to reduce case numbers. Employees should not be discouraged from raising concerns, disadvantaged for doing so, denied a fair opportunity to explain their position or pressured to accept an outcome they do not understand. A complaint treated as an inconvenience to be neutralised can become a broader dispute about process, trust and treatment.

Nor is informality always appropriate. Serious allegations, safeguarding concerns, substantial power imbalances, suspected retaliation, repeat failures and matters potentially engaging statutory duties may require independent decision-making, formal investigation or specialist advice. Proportionality does not mean one pathway for every case; it means a reliable basis for deciding which pathway is justified and recording why.

The strongest counterargument to a 180-day management model is that six-month limits may encourage parties to wait, making a formal internal timetable unnecessary. That is possible. Yet the more immediate risk for employers is assuming that a longer legal clock removes the need for prompt action. It does not change the commercial and evidential advantages of early engagement: recollections are fresher, documents are easier to preserve, relationships are more recoverable and poor decisions can be corrected before they harden into wider conflict.

Employers should therefore monitor indicators that reveal whether their process is working: time to first response; material matters unresolved at 28 and 90 days; repeat complaints; use of adjustments; sickness absence or turnover after significant conflict; and matters that escalate externally. None of these measures proves fairness on its own. Together, they can identify recurring delay, inconsistency or managerial avoidance.

The immediate task is to test whether managers can evidence fair process in the decisions most likely to generate conflict: probation, performance, sickness absence, flexible working, pay, scheduling, grievance, discipline, redundancy and dismissal. The October reform extends the clock. The underlying management principle remains the same: the best opportunity to resolve a workplace problem is usually close to when it begins.
