A Garden Leave Letter is a formal document issued by an employer in England and Wales to an employee who has given or been given notice of the termination of their employment, exercising the employer's contractual right to require the employee not to attend work or perform their duties during some or all of the notice period while continuing to receive their full salary and contractual benefits. The employee remains an employee throughout the garden leave period and continues to owe duties to the employer — principally the implied duty of good faith and fidelity — but is excused from performing their role.

The term 'garden leave' derives from the idea that the employee is at home tending their garden while still on the employer's payroll. Although the term has no statutory definition in England and Wales, the practice has been extensively considered by the English courts. The leading case on the enforceability of garden leave is William Hill Organisation Ltd v Tucker [1998] IRLR 313, in which the Court of Appeal held that an employer could not lawfully prevent a senior employee from working during his notice period unless the contract of employment contained an express garden leave clause. The Court held that, at common law, an employee doing a job requiring the maintenance of specialist skills has the right to work during the notice period — and that the employer cannot simply warehouse the employee and deny them the opportunity to exercise their professional functions.

Following William Hill v Tucker, garden leave provisions became standard in the contracts of senior employees, executives, and those in roles involving significant client contact or access to confidential information. Today, garden leave clauses are routinely included in the contracts of sales staff, account managers, senior executives, fund managers, traders, and other employees whose departure could cause significant commercial harm if they were to join a competitor immediately.

The practical effect of garden leave is to prevent the departing employee from accessing confidential information, maintaining contact with clients and colleagues, and building relationships that could benefit a future employer. It also limits the employee's ability to work for a competitor during the notice period, since working for another employer while still employed would typically breach the implied duty of fidelity. This makes garden leave a powerful tool for protecting the employer's business interests — often more powerful in practice than post-termination restrictive covenants, which can be difficult to enforce if drafted too broadly.

A garden leave letter is appropriate whenever an employer in England and Wales wishes to invoke a contractual garden leave clause following an employee's resignation or the employer's decision to terminate the employment. The letter should be issued promptly — ideally on the same day that the notice is given or received — to minimise the time during which the employee has access to clients, confidential information, and colleagues.

Garden leave is most commonly used in the following situations. First, where a senior employee, executive, or key commercial person resigns to join a competitor: in this situation, garden leave prevents the employee from soliciting clients or colleagues during the notice period, using their remaining access to confidential information to prepare their departure, or conducting a 'soft transition' to the new employer whilst still employed. Second, where an employer is making an employee redundant and wishes to protect confidential information, key client relationships, or commercially sensitive information during the notice period. Third, where an employee has been involved in a disciplinary matter and the employer believes that their continued presence in the workplace would be disruptive or risks harm to the business. Fourth, where an employee has a senior or fiduciary role — such as a director, fund manager, or key account manager — whose departure is likely to have a significant commercial impact if they were able to work their notice in the usual way.

Before issuing a garden leave letter, the employer must verify that the employee's contract of employment contains an express garden leave clause that clearly entitles the employer to impose garden leave. Without such a clause, imposing garden leave may itself constitute a breach of contract. Employers should also consider whether the length of the garden leave period is proportionate to the legitimate business interests being protected, since courts have held that overly long garden leave may be unenforceable or will reduce the scope of any post-termination restrictions that can be enforced.

The garden leave letter should be accompanied by practical steps to limit the departing employee's continued access to confidential information, including the suspension of access to IT systems, email accounts, and physical premises.

A well-drafted garden leave letter for use in England and Wales should contain a number of key elements to ensure that the arrangement is legally enforceable and that the employer's business interests are adequately protected.

First, the letter must cite the express contractual garden leave clause that authorises the employer to impose garden leave. As established in William Hill Organisation Ltd v Tucker [1998] IRLR 313, garden leave cannot lawfully be imposed in the absence of an express contractual right to do so (except by mutual agreement). The letter should identify the specific clause by reference to the relevant clause number and the date of the employment contract.

Second, the letter must confirm the full details of the notice period: when notice was given, the duration of the contractual notice period, and the last day of employment. The garden leave period runs from the date specified in the letter to the last day of employment, and this should be clearly stated.

Third, the letter must confirm that the employee will continue to receive their full salary and contractual benefits throughout the garden leave period. This is fundamental to the enforceability of garden leave — an employer who fails to pay salary and benefits during garden leave may be in repudiatory breach of contract. The benefits to be continued should be listed specifically, including any pension contributions, private health insurance, life assurance, and other material contractual benefits.

Fourth, the letter must set out the employee's obligations during garden leave, including: the prohibition on working for another employer or carrying on a competing business without the employer's prior written consent; the obligation to maintain confidentiality in respect of the employer's trade secrets and confidential business information; the obligation to remain available to assist with handover matters when reasonably requested; and the obligation not to make disparaging statements about the employer.

Fifth, the letter must address the practical arrangements for the return of company property — including laptops, mobile devices, access cards, and documents — and the withdrawal of access to company IT systems and communications from the commencement of garden leave. Immediate suspension of IT and system access is critical to prevent the employee from downloading or transmitting confidential data during the garden leave period.

Sixth, where the employee's contract contains post-termination restrictive covenants (such as non-compete, non-solicitation, and non-poaching clauses), the letter should remind the employee of these obligations and confirm that the period of garden leave served will be credited against the duration of any post-termination restrictions, as the courts will take the garden leave period into account when assessing the reasonableness of such restrictions.
