Introduced in 1998 The Working Time Regulations 1998 (WTR) in line with the European Working Time Directive, continue to remain effective in the modern day. Despite no longer being a part of the EU, there have been some amendments to the WTR, ensuring these laws continue to be followed by all businesses in the UK.

These laws set in stone the rules employers must following regarding working hours, breaks at work and paid holidays for all staff.

In this article we explain everything you need to know about the WTR and how to ensure compliance with these crucial employment laws. In addition, we will touch on the use of HR software and how this can support you in staying legally compliant with UK employment laws.

What does the law say?

The WTR Applies to all employees and workers. Workers are individuals who work under a contract to personally perform work or services. Includes temporary workers, agency workers, freelance workers. But does not apply to those who are self-employed.

The WTR cover the following topics, providing exact rules on:

  • Weekly working hours

  • Daily working hours

  • Rests and breaks during and between working hours

  • Paid holiday time

  • Working hours rules for young workers

The laws were introduced in a bid to protect workers, to create fair working places and practices.

Maximum weekly hours

In general, without considering any exemptions, workers can not be required to work more than 48 hours per week on average. This is typically calculated over a 17-week period.

The worker can choose to ‘opt out’ of the maximum working hours but can not be required to do this by their employer. There are specific restrictions on whether a worker can choose to opt out or not. The government have a dedicated page regarding ‘opting out’.

Required rest breaks from working

Rest breaks are considered uninterrupted time away from working (whatever that may be). The WTR require a minimum of a 20-minute rest break in a working day of more than 6 hours.

Workers should also have a break of at least 11 hours between working days. For breaks during a working week, this either needs to be a 24-hour uninterrupted break or at least a 48 hour break each fortnight.

Also included in the Working Time Regulations 1998 is paid holiday allowances. The current allowance for workers in the UK is 28 days of paid holiday per year, including bank holidays. More details on this, specifically for different working patterns can be found in our guide on holiday allowances.

Working hours for children and young people

When hiring young workers or children, but more specially teens, they can only begin to start working a full-time job once they have reached school leaving age. At this point they will then be permitted to work a 40-hour work week.

Children in the UK can begin to work a part-time job from the age of 14. However, their working hours will differ depending on whether they are working during school term time or during school holidays. When hiring a child between 14-17 it is important to check with your local council regarding the relevant rules.

Exemptions for types of workers

In industries where longer hours may be required, there are exemptions. For example:

  • Doctors

  • Armed forces

  • Police force

  • Security and surveillance staff

  • Workers in transport (sea, air and rail)

Are subject to specific exemptions based on the requirements of their job description and the industry they work within.

What is considered ‘working’

The term ‘working’ under the Working Time Regulations 1998 includes different ways in which a worker may spend their time at work. This means that working includes:

  • Training

  • Working abroad

  • Working lunches

  • Overtime required by employers

  • Any other working time that is mentioned specifically in their employment contract

This is especially important for you to be aware of if you may, for example, require your employee to complete extra training as part of their working week. Or they have been invited to a working lunch with clients. These moments need to be calculated within their maximum working hours.

Consequences for employers failing to adhere to WTR

For employers who fail to comply with the Working Time Regulations 1998, there are potentially serious consequences.

Aside from the potential reputational damage of the business, the Health and Safety Executive (HSE) and local authorities will investigate complaints against businesses. With some cases going to employment tribunal, resulting in payments of compensation or HSE fines.
