Working Time Regulations

The Working Time Regulations 1998 (WTR) set out rules on how long employees and workers can be asked to work — and the rest and holiday breaks they are legally entitled to.

Employers must take care to comply with these rules to avoid penalties, disputes, or tribunal claims. At Franklins Solicitors, we advise businesses on how to implement working time rules fairly and effectively, including opt-out agreements, shift planning, and minimum wage compliance.

Key Rights Under the Working Time Regulations

The Working Time Regulations apply to most workers in the UK and cover the following core areas:

1. Maximum Weekly Working Hours

Workers must not be required to work more than 48 hours per week, averaged over a 17-week reference period — unless they have voluntarily opted out in writing.

2. Daily Rest Periods

Workers are entitled to a rest period of at least 11 consecutive hours in every 24-hour period during which they work.

3. Weekly Rest

Each worker is entitled to at least 24 hours’ uninterrupted rest per week, or 48 hours’ rest per fortnight.

4. Rest Breaks During the Working Day

If a worker’s daily shift lasts more than six hours, they are entitled to a minimum 20-minute rest break, which should not be taken at the start or end of the working day.

5. Paid Annual Leave

Workers are entitled to a minimum of 5.6 weeks of paid holiday per leave year (which includes public holidays, unless stated otherwise in their contract). For full-time employees, this equates to 28 days.

Working Time and National Minimum Wage (NMW) Compliance

Correctly classifying ‘working time’ is essential when calculating whether an employee has received the National Minimum Wage or National Living Wage. Common issues include:

  • Whether time spent on call, travelling between assignments, or attending mandatory training counts as working time
  • Handling sleep-in shifts for care workers
  • Ensuring zero-hours workers receive correct rest breaks and holiday entitlement

Misclassifying time can lead to back pay claims, HMRC investigations, and reputational damage.

Who Is Covered by the Working Time Regulations?

The WTR applies to:

  • Full-time and part-time employees
  • Agency workers
  • Freelancers and some contractors
  • Shift workers
  • Night workers
  • Young workers

There are exceptions for sectors such as emergency services, armed forces, domestic servants, and certain transport workers, where different rules may apply.

Managing Opt-Out Agreements

Employees can choose to opt out of the 48-hour weekly limit, but this must be done:

  • Voluntarily
  • In writing
  • With the right to withdraw consent with notice (usually one week)

We can help employers:

  • Draft legally compliant opt-out agreements
  • Keep accurate records for audit purposes
  • Ensure no undue pressure is placed on workers to sign

Avoiding Breaches of the Working Time Regulations

Breaching the WTR can result in:

  • Claims to an Employment Tribunal
  • Compensation for missed breaks or unpaid holiday
  • Enforcement action by the Health and Safety Executive (HSE)
  • Damage to employee morale and retention

Even unintentional non-compliance can be costly. That’s why proactive legal advice and robust internal procedures are essential.
