Employment contracts are legally binding agreements that outline the terms and conditions of the relationship between an employer and an employee. These terms can involve pay, working hours, job responsibilities, benefits and more. However, over time, circumstances might arise which necessitate changes to an existing employment contract. Managing these changes lawfully is essential to avoid disputes and ensure ongoing compliance with employment law.
At Stephensons, we have significant expertise in advising individuals on their employment rights and the legal implications of proposed contractual changes. Whether your employer is seeking to update your terms or you wish to initiate changes yourself, it is vital to understand your position under UK employment law.
What counts as a change to an employment contract
A change to an employment contract can involve altering any of the terms originally agreed between an employer and employee. Common changes include:
- Adjustments to pay or bonus structures
- Modifying working hours or shift patterns
- Changing job duties or job title
- Relocation to a different office or worksite
- Modifications to disciplinary or grievance procedures
- Altering holiday entitlement or benefits
Such changes can be proposed for various reasons, including restructuring, changes in business operations, or economic pressures. Regardless of the reason, changes to employment contract terms should be approached with caution and legal guidance.
When a change is legally valid
To be lawful, any change to an employment contract must be agreed upon by both the employer and the employee. An employer cannot unilaterally impose a new term without the agreement of the employee, unless there is an express contractual right to do so. If a unilateral change is made without consent, the employer could be in breach of contract, potentially giving rise to claims including constructive dismissal.
Some contracts include flexibility clauses that allow employers to make certain changes without consent. However, these clauses are subject to limitations and must be used reasonably and in good faith. Significant changes that are not properly managed can result in serious legal consequences.
Consultation and agreement
Where a change is proposed, the employer must engage in consultation with the affected employee(s). This involves explaining the reasons for the change, listening to feedback, and attempting to reach agreement. A variation in terms should always be confirmed in writing, ideally by issuing a revised contract or an amendment letter that both parties sign to acknowledge their agreement.
If employees do not agree to the changes, the employer may consider terminating the original contract and offering re-engagement under new terms. While potentially lawful, this approach must follow a fair dismissal process, including proper consultation and notice. Failure to do so may result in unfair dismissal claims.
Your rights as an employee
As an employee, you have the right not to have your employment contract changed without your consent. If changes are imposed without agreement, you may have several options, including:
- Raising a grievance internally with your employer
- Refusing to work under the new terms and maintaining the original contract
- Claiming breach of contract or unlawful deduction from wages (if the change involves pay)
- Resigning and claiming constructive dismissal in certain circumstances
The appropriate course of action will depend on the specific facts of your case and the nature of the change involved. Legal advice is strongly recommended before taking any action, especially in situations involving resignation or claims to an employment tribunal.
Time limits and tribunal claims
Claims relating to changes to employment contract terms are generally subject to strict time limits. If you believe you have been unfairly dismissed or subjected to unlawful pay changes, you typically have three months (minus one day) from the date of the act to bring a claim to an employment tribunal. Early conciliation through Acas is usually a required step before lodging a formal claim.
It is important not to delay in seeking legal advice if you feel your contract has been improperly altered. At Stephensons, we can assess your situation and provide clear guidance on your rights and any potential claims you may pursue.
