What Every Employer Should Know About Part-Time Work in England

Table of Contents

As an employer, you may employ staff on a full-time or part-time basis. A part-time worker is an employee who works fewer hours than a full-time worker. Nevertheless, your part-time staff have the same rights as your full-time staff. Hence, you should not treat them any less favourably just because they work part-time. This article will explain what you, as an employer, need to know about part-time working in England. 

Who is a Part-Time Worker?

While there is no legal definition of a part-time worker regarding the number of hours they work, a full-time worker is someone who works at least 35 hours per week. Therefore, any member of your staff who works less than this is likely to be a part-time worker. 

What Rights Do Part-Time Workers Have? 

Part-time workers have the same rights as equivalent full-time workers or comparators. Therefore, you should treat your part-time workers the same way in terms of their:

  • pay rates for salary, sick pay, maternity and paternity pay, and adoption pay;
  • holiday, maternity, paternity and adoption leave;
  • pension rights, including benefits and opportunities;
  • career development opportunities, which include training, promotion and transfer;
  • redundancy selection and pay; and 
  • career break opportunities.

You should note that there are some differences between how rights are applied to part-time workers, such as where these are treated on a pro-rata basis. This means part-time workers will get the same right in proportion to the time worked.

The law also protects your part-time workers from being treated differently or less favourably because they have:

  • made a complaint about you treating a part-time worker less favourably than a full-time comparator; 
  • supported a complaint someone made about treating a part-time worker less favourably than a full-time comparator; or
  • where it is thought that they did either of the above.

What is a Comparator?

Employees working for you part-time should be treated no less favourably than their full-time comparator. A full-time comparator is someone who:

  • is on the same contract type as the part-time worker;
  • has qualifications, skills and experience similar to the part-time worker; and 
  • is working in the same organisation.

To ensure that you are not treating your part-time employees less favourably than their full-time comparators, you should focus on the individual terms and conditions in your part-time workers’ contracts rather than on the contract holistically.   

When is an Employer Allowed To Treat Part-Time Workers Differently?

There are instances where you can treat your part-time worker less favourably, providing you can show ‘objective justification’. Objective justification demonstrates that you have a good reason for treating your part-time workers differently or less favourably. To show objective justification, you need to prove that the different treatment is:

  • towards a legitimate business objective or aim for your business; and
  • is a method to achieve this, which is needed and appropriate. 

For example, if you provide your full-time staff with gym membership but the cost of doing so is not in proportion with the benefits you provide, you may have a good reason not to give this to your part-time staff.

What Happens if You Treat a Part-Time Worker Less Favourably?

If you have treated a part-time employee less favourably when you should not have, you should try to resolve the matter informally. However, where this does not resolve the issue, your part-time employee has a legal right to ask you for a written statement of your reasons for less-favourable or different treatment. 

You must give them your written statement within 21 days of their request. If your explanation does not appear to be one with objective justification, your employee may take you to an employment tribunal for an employment claim. The employment tribunal will consider your reason and whether you provided your employee with your reasons within 21 days.

Key Takeaways

As an employer, you should not treat your part-time workers differently or less favourably than their full-time comparators. This means you should afford your part-time workers the same rights on a pro-rata basis. Nevertheless, you can only treat your part-time workers less favourably or differently where you have a good reason to. If you do not afford your part-time workers their rights, they may initiate a claim against you at an employment tribunal.
