Tips for Businesses

Ensure contracts are issued on or before an employee’s start date. Review templates regularly to reflect current law. Include clear notice periods, variable pay terms, and any probationary conditions. Where roles change, update contracts or issue a side letter promptly. Seek legal input before including restrictive covenants.

Employment contracts form the foundation of the relationship between you and your staff. Whether written or verbal, these legally binding agreements set out the rights and obligations of both parties and help prevent misunderstandings that could lead to disputes or employment tribunal claims. The law requires employers to provide detailed written information to employees and workers from day one of their employment. Understanding what must be included in your employment contracts- and what should be included as good practice, is essential for compliance and effective workforce management. 

This article will explain the key terms in an employment contract and some others you may wish to include.

What Types of Terms Should You Include in an Employment Contract?

Ordinarily, an employment contract consists of the following types of terms.

Express Terms

These are agreed upon in writing and are specific to the employee’s job, such as the pay rate and the working hours.

Statutory Terms

Statutory terms are those that are found more widely in employment law.

Implied Terms

These are generally obvious terms and are not required to be stated in writing, such as being polite to customers. They could also be custom and practice, such as things that tend to be known as good practice within your industry.

Incorporated Terms

These are terms that are placed elsewhere but are part of the employment contract. For example, those in the staff handbook.

Written Terms Which You Must Include in Your Employment Contract

Your employees and any workers who started work on 6 April 2020 or after are legally entitled to written terms. 

Written terms are formally called a ‘written statement of employment particulars’. This is not the entire employment contract but just one part of it. These summarise the main terms of the employees’ employment such as their working hours and their pay rate. Everything contained within them must be legally correct.

Several elements make up a written statement of employment particulars. 

1. The Principal Statement

The written terms contain a principal statement that should detail:

  • your name and address as the employer;
  • the name of your employee or worker;
  • the start date of their employment, including whether any previous service counts towards this;
  • the title of the job or a description of it;
  • their place of work. This may be a local area rather than a specific address if you intend your business to grow;
  • their pay and working hours;
  • the specifics of their holiday leave and pay, as well as how this is worked out in case they leave the job;
  • the specifics of sick leave and pay, as well as any other paid leave they are entitled to or where to find this information;
  • any additional benefits they are entitled to, including those they are legally entitled to;
  • the length of the employment and what the notice period is for both you and your employee;
  • the length and conditions of any probationary period;
  • any terms applying to any overseas work; and 
  • any mandatory training.

2. The Wider Written Statement 

This contains the terms that you do not need to provide immediately. 

You must include these other written terms in your employee’s employment contract. However, you should provide them within two months of the employee starting their employment. These are termed instalments.

Terms that can be provided later but must be included are:

  • arrangements about pensions or where to find this information;
  • ‘collective arrangements’, which are terms and conditions that apply to other employees as well;
  • arrangements about training, which is not mandatory, or where to find this information; and 
  • disciplinary and grievance procedures, as well as any disciplinary rules.

Written Terms That Are Helpful to Include in an Employment Contract

While there are written terms that must by law be provided to an employee as part of their employment contract, other pieces of information are helpful to provide in writing. By doing so, you and your employee should be clear about your responsibilities and your rights. These can include:

  • what the job offer is;
  • the method of paying the employee; and
  • what you expect of your employee regarding standards and the consequences of not meeting these.

You may also decide to include restrictive covenants in your employment contract. These restrict your employee when they leave your employment from specific actions that may affect your business.

Common Mistakes to Avoid in Employment Contracts

When drafting employment contracts, employers often make mistakes that can lead to legal complications. Common errors include:

  • using outdated templates that do not reflect current legal requirements;
  • failing to specify the correct notice periods or making them unclear can cause disputes when employment ends;
  • including unenforceable restrictive covenants that are too broad or not reasonably necessary to protect legitimate business interests;
  • omitting details about variable pay, such as commission, bonuses, or overtime rates;
  • not updating contracts (or issuing side letters) when an employee’s role, hours, or pay changes; and
  • copying contracts from other jurisdictions, such as Scotland or Northern Ireland, which have different employment laws.

Taking care to avoid these mistakes will help ensure your employment contracts are legally compliant and fit for purpose.
