Managing Fatigue Grievances in Construction and Transport

In construction and transport, the conversation about fatigue has long been framed as a health and safety issue. Fatigue policies sit in safety management systems. Incidents trigger RIDDOR reports. The responsibility lies with the operations team.

That framing is changing. The conditions for fatigue-related grievances in both sectors have rarely been more pronounced. Regulatory scrutiny of working hours is intensifying, overall workplace dispute volumes are rising sharply; Acas early conciliation receipts grew 40% between July 2023 and September 2025. Now the Employment Rights Act 2025 has made formal escalation more accessible to workers than ever before. The result is a workforce more likely to raise concerns about scheduling, rest periods, pressure to work beyond legal limits, and the cumulative impact on their health through formal grievance channels rather than suffering them in silence.

For HR teams in construction and transport businesses, this shift matters. Fatigue grievances have their own distinct characteristics: they sit at the intersection of employment law, health and safety legislation, and sector-specific regulations. They require a dedicated grievance management system that treats cases seriously, records them consistently, and links them to broader compliance obligations.

This post sets out why fatigue grievances are likely to grow, what makes them complex to handle, and how the right case management approach helps organisations stay on the right side of the law.

The Fatigue Grievance Landscape

The regulatory environment in both sectors has tightened considerably in recent years, and enforcement is becoming more active.

In transport, HGV drivers are subject to strict driving hours rules under both UK and retained EU regulations. Drivers are limited to nine hours of driving per day (extendable to ten hours a maximum of twice per week), a weekly cap of 56 hours, and a fortnightly maximum of 90 hours. Tachograph compliance is mandatory, and the Driver and Vehicle Standards Agency (DVSA) actively enforces these limits. In the first three quarters of the 2024/25 financial year alone, DVSA officers conducted over 9,500 driver hours checks on HGVs, with 265 drivers found in breach. Moreover, enforcement is increasingly driven by data, including Automatic Number Plate Recognition technology to identify non-compliant operators remotely.

In construction, the picture is different but equally pressured. There are no sector-specific driving hours rules equivalent to those in transport, but construction workers are covered by the Working Time Regulations 1998, which set the 48-hour average weekly working limit. Long hours culture, project deadlines, and the use of self-employed and agency labour have historically made enforcement difficult. The HSE's Construction Statistics for Great Britain, 2025 show that the fatal injury rate in construction is 1.92 per 100,000 workers, around 4.8 times the all-industry rate, with 79,000 workers suffering from work-related ill health in the most recent period. Fatigue can often be an underlying factor in incidents in physically demanding roles.

Alongside sector-specific regulation, the Employment Rights Act 2025 has changed the wider employment law landscape. The Act strengthens worker protections, expands the scope of protected disclosures under whistleblowing legislation, and simplifies trade union recognition, all of which make it more likely that workers who have been reluctant to raise concerns formally will now do so. HR teams in both sectors should expect grievance volumes to increase, and fatigue to feature more prominently among them.

What Makes Fatigue Grievances Different

A fatigue grievance is not simply a complaint about being tired. When a worker raises one formally, they are typically alleging one or more of the following:

• That their employer scheduled them in breach of legal working hours limits
• That they were pressured to work beyond their contracted hours or statutory rest entitlements
• That fatigue contributed to a workplace injury or near miss for which they hold the employer responsible
• That their concerns about fatigue were previously raised informally and ignored
• That inadequate rest periods are affecting their physical or mental health

This makes fatigue grievances qualitatively different from most other HR cases. They often have a health and safety dimension running alongside the employment law one. They may trigger obligations under RIDDOR. They can overlap with whistleblowing protections if the worker is raising concerns about regulatory non-compliance. And they frequently involve documentary evidence - tachograph data, rota records, shift logs - that needs to be preserved and interrogated as part of the investigation.

For HR teams used to handling grievances about pay, conduct, or interpersonal conflict, fatigue cases require a broader set of skills and a more careful evidence-gathering process.

The Case Management Challenges in Practice

Establishing the Facts

Investigating a fatigue grievance in transport means accessing and interpreting tachograph data, driver hours logs, and scheduling records. In construction, it means pulling rota data, timesheets, and any relevant site attendance records. If the complaint relates to pressure rather than technical breaches, such as a foreman pushing the team to start before permitted hours, or a project manager scheduling back-to-back shifts without adequate rest, the evidence base is less clear-cut and witness testimony becomes more important.

The investigation also needs to establish whether any regulatory limits were actually breached, or whether the grievance is about the cumulative experience of working at the edge of those limits. Both are valid but they require different responses.

Linking HR and Health & Safety Records

One of the most common case management failures in this area is that the HR team handles the grievance without checking whether there are related health and safety records - incident reports, near-miss logs, or RIDDOR notifications - that are relevant to the complaint. If a worker is raising a fatigue grievance following an injury, and the employer has a separate RIDDOR report on file for the same incident, those records need to be considered together.

In practice, this cross-functional coordination is difficult unless there are shared systems or clear protocols for flagging related cases between HR and health and safety functions.

Protecting the Worker During Investigation

Under the Acas Code of Practice on Disciplinary and Grievance Procedures, employers are required to investigate grievances without unreasonable delay and to protect workers from detriment as a result of raising a complaint. In fatigue cases, this may mean temporarily adjusting the worker's schedule while the investigation is underway, which has operational implications in sectors where shift coverage is already stretched.

Managing the Audit Trail

Fatigue grievances carry a higher escalation risk than most standard HR case types. A worker who suffers detriment, like disadvantageous rescheduling, management pressure or dismissal, after raising a fatigue complaint has grounds for an employment tribunal claim, and where that claim succeeds, compensation is uncapped. Where the underlying concern involves a breach of the Working Time Regulations, the employer may simultaneously face scrutiny from the DVSA (in transport) or the HSE (in construction), independent of any tribunal outcome.

The risk compounds further where the worker's concerns meet the threshold for a protected disclosure: whistleblowing claims at employment tribunal rose 102% year-on-year in the most recent statistics, from 888 to 1,796 complaints, making them the fastest-growing major claim type. Against a backdrop of over 58,000 live single claims at the end of 2025, a 49% annual increase, cases that do reach tribunal are taking significantly longer to resolve, prolonging financial and reputational exposure for employers who cannot produce a defensible case record. Every stage of the investigation needs to be documented in a way that is defensible under scrutiny.

Treating Fatigue Grievances as a Distinct Case Type

Organisations handling a meaningful volume of cases in construction or transport should consider whether fatigue grievances warrant their own categorisation within their HR grievance management system.

Treating them as a distinct case type has practical advantages:

Consistent process. A dedicated case pathway ensures that fatigue grievances are always investigated in the same structured way, with the right evidence-gathering steps built in from the start, including prompts to pull scheduling data, check for related health and safety records, and confirm whether any regulatory limits were involved.

Better data. Categorising fatigue cases separately produces reporting data that is actually useful. If fatigue grievances are logged simply as "other" or bundled with general working conditions complaints, patterns become invisible. Distinct categorisation allows teams to identify whether cases cluster around specific sites, shifts, teams, or line managers and to act on those patterns before they become systemic.

Clearer accountability. Fatigue cases often involve both HR and health and safety functions. A dedicated case type makes it easier to define and document which function is leading, which is providing input, and what information-sharing protocols apply.

Regulatory readiness. In the event of an DVSA audit, HSE inspection, or employment tribunal, having a clear and complete case record for each fatigue grievance, including the investigation steps taken, the outcome, and any corrective action, is the difference between a confident response and an exposed one.

How Workpro Supports Fatigue Grievance Management

At Workpro, we work with organisations across complex, regulated sectors where grievance management needs to do more than track a complaint from open to closed.

Our HR case management software allows organisations to configure custom case types, meaning fatigue grievances can be set up with their own process templates, evidence-gathering prompts, and escalation rules. Each case generates a complete audit trail automatically; every action, every document, every communication, timestamped and accessible when it matters.

Where fatigue cases overlap with health and safety, Workpro's search capability means related records, whether a concurrent absence case, a RIDDOR-related incident, or a previous informal concern, can be associated with the active grievance. Investigators have a complete picture rather than a fragmented one.

Workpro's reporting and analytics features allow HR teams to track fatigue case volumes, resolution times, and outcomes over time, and to spot early indicators of systemic scheduling or culture problems before they generate further cases. That kind of forward-looking visibility is increasingly what regulators and senior leadership alike expect from HR operations in high-risk sectors.

Conclusion

Fatigue grievances in construction and transport are not going away. Regulatory scrutiny of working hours is increasing in both sectors, the Employment Rights Act 2025 has strengthened worker protections, and a workforce that is better informed about its rights is more likely to use formal channels when those rights are not being respected.

For HR teams, the challenge is to manage these cases with the rigour they require, not treating them as standard grievances, but as a distinct case type with its own evidence requirements, cross-functional dependencies, and compliance implications.

Organisations that build that capability now, through both clear process design and capable grievance management systems, will be far better placed when the volume and complexity of fatigue-related cases continues to grow.
