What it means
When a key employee resigns to join a rival, allowing them to remain at their desk poses a major risk. They might copy client lists, share proprietary strategies, or encourage colleagues to jump ship.
To neutralise this threat, employers place the individual on gardening leave. The worker remains technically employed, meaning their contract rules and confidentiality clauses still apply, but they must stay home and tend to their garden rather than coming into the office.
During this time, the employee receives their regular salary and benefits. In exchange, they cannot work for anyone else, contact clients, or access company systems.
This cooling-off period ensures that by the time they finally start their new job, any commercial secrets they carry are outdated and far less useful to a competitor. For non-finance managers, understanding gardening leave is vital when budgeting for staff departures.
Even though the departing employee is not producing any output, their salary remains a fixed overhead for the duration of the notice period. Furthermore, if you need to hire an immediate replacement, you may face a period of paying two people for the exact same role while the first person serves out their leave at home.
This practice is most common in senior management, sales, finance, and technology roles where access to confidential data gives a distinct competitive advantage. While it can feel frustrating for both sides, it acts as an essential insurance policy for company assets, balancing the right of an individual to change jobs with the legitimate need of a business to protect its competitive edge.
In practice
Real-world examples.
Example
TechCo placed its departing Chief Technology Officer on a three-month gardening leave, continuing to pay their £10,000 monthly salary. This prevented the CTO from sharing upcoming product roadmaps with a direct competitor immediately.
Example
A boutique marketing agency used a one-month gardening leave for a senior account manager who resigned. By keeping them away from key clients, the agency secured existing contracts and transitioned accounts safely to other team members.
Example
A regional bank enforced a six-month gardening leave for an investment director moving to a rival firm. This extended pause ensured that strategic financial portfolios and client lists became outdated before the director started the new job.
Think of it
“Imagine a head chef leaving a famous restaurant to open a rival diner across the street. Instead of letting them stay in the kitchen for their final month to memorise the secret recipes, the owner pays them to stay home, keeping the recipes safe.
Formula
Calculation
Total Gardening Leave Cost = Monthly Salary * Notice Period Duration in Months. Example: A departing manager with a £5,000 monthly salary placed on a 3-month gardening leave costs the business £5,000 * 3 = £15,000 in continued payroll overhead.Case study
Seen in the real world.
Apex Financial, a mid-sized wealth management firm based in Manchester, faced a major strategic risk when their top portfolio manager announced their resignation to join a larger competitor. The manager held direct relationships with clients holding over £50 million in assets.
To prevent client poaching, Apex invoked the gardening leave clause in the manager's employment contract. For the next three months, the manager received their full monthly salary of £6,000, totalling £18,000, but was stripped of system access and prohibited from contacting clients.
During this three-month buffer, Apex reassigned the client accounts to two junior managers, successfully retaining 95 percent of the assets under management. Meanwhile, the competitor had to wait three months for the new hire to start, by which time Apex had solidified its relationships with the key clients. Although Apex paid £18,000 for an employee who did no work, the financial cost was minimal compared to losing millions in client funds.
Watch out
Common mistakes.
- Assuming the employee is legally free to start their new job immediately, which can breach contract terms.
- Failing to budget for the continued salary and benefits overhead during the notice period.
- Confusing gardening leave with redundancy, as the employee is still officially contracted and cannot work elsewhere.
Questions
People also ask.
Can an employee work for a competitor while on gardening leave?
No. The employee is still under contract with their current employer and cannot take up new employment until the leave period officially ends.
Does the employee continue to accrue holiday during gardening leave?
Yes. Because the employment contract remains active, standard statutory employment rights, including holiday accrual, continue to apply.
Is gardening leave only for senior executives?
Not exclusively. While common in senior roles, it applies to any employee who handles sensitive data, intellectual property, or key client accounts.
