Fatigue and Working Time Directive Management

Track hours worked, monitor rest periods, and enforce WTD compliance across your entire workforce. Four enforcement modes let you start with visibility and scale up to automated access control.

The problem with managing fatigue on construction sites

Construction workers routinely work across multiple sites and multiple employers. A worker finishes a 12-hour shift on your site, drives to another site, and starts another shift with barely four hours of rest. You have no visibility into it because their hours on the other site are invisible to you.

The Working Time Regulations 1998 set clear limits: a 48-hour average working week, 11 consecutive hours of rest in every 24-hour period, and a 24-hour uninterrupted rest period every 7 days. But on most construction sites, compliance is tracked on paper, if it is tracked at all. Opt-out agreements are buried in filing cabinets. Nobody reviews them.

Fatigue-related incidents are among the most preventable causes of harm in construction. The HSE estimates that human fatigue contributes to up to 20% of accidents on major roads and is a significant factor in workplace incidents. Without real-time monitoring of hours and rest periods, principal contractors are left relying on self-reporting and hoping for the best.

How AttendIQ handles fatigue and WTD compliance

AttendIQ monitors hours and rest periods automatically from attendance data, giving you real-time visibility into fatigue risk across your workforce.

Four enforcement modes

Choose the level that suits your organisation. Off disables monitoring entirely. Monitor logs violations without alerting anyone. Active warns workers and supervisors when limits are approached. Full blocks site access when minimum rest periods have not been met.

Rest period tracking

AttendIQ calculates the gap between every clock-out and the next clock-in for each worker. If the rest period falls below your configured minimum, the system flags it immediately. No manual checks. No reliance on workers self-reporting their hours from other sites.

48-hour opt-out register

A built-in digital register for WTD opt-out agreements. Record which workers have opted out, when the agreement was signed, and whether it remains valid. Opted-out workers are still tracked and reported, but exempt from the 48-hour weekly average enforcement.

Weekly overtime monitoring

Track weekly hours against configurable thresholds. See which workers are approaching limits before they breach them. Weekly overtime data feeds into payroll calculations, giving you a single source of truth for both compliance and pay.

How it works

1

Configure your policy

Set your enforcement mode (off, monitor, active, or full), minimum rest hours between shifts, and weekly hour thresholds. Enable the feature per organisation using the fatigue management feature flag.

2

Automatic monitoring

As workers clock in and out, AttendIQ continuously calculates hours worked and rest periods. Violations are detected in real time and logged as fatigue events. Workers approaching limits trigger early warnings.

3

Report and enforce

Review fatigue reports by site, worker, or time period. Export violation data for audits. In full enforcement mode, workers who have not met minimum rest requirements are blocked at the gate until compliance is restored.

Frequently asked questions

How does AttendIQ handle 48-hour opt-outs under the Working Time Directive?

AttendIQ includes a built-in 48-hour opt-out register. Workers who have signed a valid opt-out agreement are flagged in the system. Their hours are still tracked and reported, but they are exempt from the 48-hour weekly average limit. Admins can see at a glance which workers have opted out, when the opt-out was recorded, and whether it remains valid. Opt-outs can be withdrawn at any time, and the system adjusts enforcement immediately.

How does AttendIQ track rest periods between shifts?

AttendIQ calculates rest periods automatically from clock-in and clock-out times. The system monitors the gap between a worker's last clock-out and their next clock-in. If the rest period falls below the minimum threshold you have configured, the system flags a violation. In active or full enforcement mode, the worker receives an alert. In full mode, site access can be blocked until the minimum rest period has elapsed.

What happens when a Working Time Directive violation is detected?

The response depends on which enforcement mode your organisation uses. In monitor mode, the violation is logged and reported but no action is taken. In active mode, the worker and their supervisor are notified with a warning. In full mode, the worker is blocked from clocking in until compliance is restored. Every violation is recorded as a fatigue event for audit purposes, regardless of the enforcement mode.

Can AttendIQ track hours across multiple sites and employers?

Yes. Because worker records in AttendIQ are not tied to a single organisation, the system can aggregate hours across every site and employer a worker is connected to. If a worker clocks 10 hours on Site A for one contractor and then clocks 8 hours on Site B for another, both sets of hours count towards their weekly total. This cross-site visibility is critical for WTD compliance, because fatigue risk does not stop at the site boundary.

What fatigue reports are available?

AttendIQ provides fatigue reports broken down by site, worker, and time period. You can see weekly hours worked, average rest periods, WTD violations by type, and workers approaching the 48-hour weekly threshold. The fatigue events log gives you a complete audit trail of every flagged incident. Reports can be exported to CSV or scheduled for automatic delivery to your inbox on a weekly or monthly basis.

Stop guessing who is fatigued. Start knowing.
