Talking Terms

An employee’s terms of employment are bound to change in numerous ways during their employment.

The most obvious examples include pay rises (annual or otherwise) and promotions. These changes usually happen by agreement and do not therefore cause legal or practical issues for employers.

On the other hand, there are changes an employer may wish to make that are not so obviously in the employee’s interest.

The starting point is to consider whether the employer’s plans will require the employment contract itself to be changed (called ‘varied’).

There are three main types of terms of employment, which are:

• Express – these are explicitly agreed between employer and employee;
• Implied – these are ‘read into’ the contract in several ways, mainly through custom and practice;
• Incorporated – these terms are those imposed by a law or collective agreement.

If the employer is intending to change a contractual term, there are three possible methods. The best option in legal and practical terms is to obtain an express agreement. This is an agreement with the employee (or employees) directly; or, where appropriate, a binding collective agreement with a trade union.

Always have the agreement (and the contract itself) in writing. Verbal agreements are legally valid but are much more difficult to prove later if challenged.

The second option is to unilaterally impose the change and hope that the employee does not challenge it.

This does leave the employer open to legal claims of breach of contract or even unfair dismissal, depending on the importance of the specific term or terms changed.

Where changes are minor or administrative, continuing to work under the new terms may suffice. Even for more substantial changes, employees will be ‘deemed’ to have consented to the change after a while (unless the employee says they are working ‘under protest’).
