Most employers want their team to actually take annual leave. It is good for the people and, in practice, good for the business. But leave requests collide with reality: peak seasons, short staffing, overlapping requests and projects with hard deadlines. When that happens, the question is how far an employer can go in saying no.
Under the Fair Work Act 2009 (Cth), the answer is built around one rule. Paid annual leave is taken at a time agreed between the employee and the employer, and the employer must not unreasonably refuse a request to take it (s 88). There is no automatic right to your preferred dates as an employee, and no automatic right to refuse as an employer. Everything turns on what is reasonable in the circumstances.
This guide walks through how that machinery works: who does what when a request is made, how the reasonableness test operates, the ways a modern award or enterprise agreement changes the rules, and where disputes typically end up. It matters most at the moments when leave gets awkward: Christmas, end of financial year, school holidays, or the employee who is quietly carrying eight weeks of accrued leave.
Who Does What in a Leave Request
A leave request brings four parties into play, each with a defined role:
- The employee: accrues the entitlement and asks to take specific dates.
- The employer: agrees to a time, proposes an alternative, or refuses, and must not unreasonably refuse a request.
- The modern award or enterprise agreement: sets the process for requesting leave, and may add rules on excessive accruals, cashing out and shutdowns.
- The Fair Work Ombudsman (FWO): the regulator that investigates alleged breaches of the National Employment Standards and publishes guidance on what is and is not allowed.
- The Fair Work Commission (FWC): the tribunal that resolves leave disputes through award and agreement dispute-resolution clauses, and hears general protections applications.
The tension in the system is between the employee's entitlement to a genuine break and the employer's need to keep the business running. The law does not pick one side. It makes the employer justify a refusal.
The Entitlement and the Request
For each year of service, a non-casual employee accrues four weeks of paid annual leave, or five weeks if a modern award or enterprise agreement defines them as a shiftworker for the purposes of the National Employment Standards (s 87 of the Fair Work Act 2009 (Cth)). The leave accrues progressively across the year, and periods of casual employment do not count toward the entitlement. Casuals generally do not accrue paid annual leave at all.
Leave can be taken only at a time the employee and employer agree on (s 88(1)). There is no minimum or maximum amount that must be taken at once: with agreement, an employee can take a part day, a single day or several weeks, as the Fair Work Ombudsman explains. The process for requesting leave is usually set out in the award, agreement, contract or a workplace policy, and awards and agreements commonly prescribe how requests are made and how much notice is expected.
When leave is taken, the employee is paid at their base rate of pay for their ordinary hours in the period (s 90(1)). Any annual leave loading comes from the award or agreement, not from the National Employment Standards. And if employment ends with leave accrued but untaken, the employer must pay it out (s 90(2)).
The Refusal Rule: What "Unreasonable" Means
Section 88(2) of the Act is the whole game: the employer must not unreasonably refuse to agree to a request by the employee to take paid annual leave. The FWO puts it in one line: an employer can only refuse a request for annual leave if the refusal is reasonable.
What is reasonable is a question of fact, but a defensible refusal has to be anchored in what approving the leave would actually do to the business, not in what the employer would prefer. The factors that typically do the work:
- Operational impact: whether approving the dates would leave the business short-staffed, breach minimum staffing, or jeopardise a critical deadline or project. Peak periods such as Christmas retail, hospitality in school holidays or end-of-financial-year accounting are the classic examples.
- Notice and timing: how far in advance the request was made, how long the leave is for, and whether backfill was practical. A request dropped at short notice in a busy period is easier to refuse than one made months ahead.
- Overlap with other leave: whether too many people in the same role would be away at once, or whether the dates clash with already-approved leave.
- The award or agreement: what it says about how requests are made, notice periods, and how leave disputes are handled.
- Alternatives: whether different dates, a shorter period or split leave would meet both sides' needs.
A refusal based on personal preference, or applied inconsistently between employees in similar roles, is hard to defend. So is refusing simply because an employee wants to use the leave they have accrued. And if the real reason for a refusal is a protected attribute, or the fact that the employee made the request at all, the refusal can cross from an industrial question into discrimination or general protections territory.
The practical discipline is documentation. Respond to requests promptly, in writing, with the specific operational impact set out. Offer an alternative where one exists. Apply the same logic to everyone. A refusal that is explained, dated and consistent is almost always defensible. A refusal that exists only in a manager's memory is where disputes start.
When the Award or Agreement Rewrites the Rules
The National Employment Standards are a floor. A modern award or enterprise agreement cannot exclude them (s 55 of the Fair Work Act 2009 (Cth)), but the Act expressly allows awards and agreements to add certain annual-leave terms, and those terms then operate alongside the NES. Three of them matter most in practice:
-
Cashing out: An award or enterprise agreement may allow employees to cash out paid annual leave, and award/agreement-free employees can agree to cash out with their employer (ss 93-94). Three conditions apply: the employee's remaining accrued balance must stay at or above four weeks, each cashing out must be by a separate written agreement, and the employee must be paid at least the full amount they would have received had they taken the leave.
-
Excessive accrual directions: Excess annual leave is typically a balance of more than eight weeks, or ten weeks for a shiftworker, as the FWO's guidance on directed leave explains. Under most awards, an employer who cannot agree with the employee on when to take the leave can direct them in writing, giving at least eight weeks' notice and no more than twelve months before the leave starts; the directed leave must be at least one week and generally cannot reduce the balance below six weeks. Award rules differ, so check the specific award. For award/agreement-free employees, an employer can require leave only where the requirement is reasonable (s 94(5)), which can include an excessive balance.
-
Shutdowns: During a shutdown such as the Christmas-New Year period, an employer can direct employees to take annual leave if the award or agreement allows it, and many modern awards have included shutdown terms in recent years. For award/agreement-free employees, an employer can require annual leave during a temporary shutdown, but again only if the requirement is reasonable (s 94(5)), as the FWO's shutdown guidance confirms.
A shutdown is not the same as a stand down. A stand down is when an employer tells employees not to work because they cannot be usefully employed for reasons outside the employer's control, such as equipment breakdown, industrial action the employer did not organise, or a natural disaster. Stand down rules sit in the Fair Work Act 2009 separately from annual leave, and the two should not be confused when you are planning the Christmas close.
When a Refusal Turns Into a Dispute
If an employee disagrees with a refusal, the first port of call is usually the dispute-resolution clause in the award or enterprise agreement, which typically requires the parties to talk and can end with the Fair Work Commission conciliating or arbitrating the matter. The FWO can also investigate an alleged breach of the National Employment Standards, including an unreasonable refusal, and can take court action where warranted.
Two situations deserve particular care:
-
Changing or cancelling approved leave: There is no general right under the Fair Work Act 2009 to cancel annual leave once it has been approved. A change should happen by agreement, or under a term in the contract, policy, award or agreement that expressly allows it. If an operational emergency genuinely requires it, talk to the employee as early as possible, offer alternatives, and think about whether the employee will lose money, for example on non-refundable travel. The employer who cancels approved leave without a basis is inviting a dispute it will struggle to win.
-
Adverse action: A request to take annual leave engages a workplace right, and the general protections provisions of the Fair Work Act 2009 protect employees from being treated adversely because they exercised one. A refusal that is really a response to the request itself, rather than to the operational impact of the dates, can expose the employer to a general protections application. This is why the documented business reason matters so much.
Where a Lawyer Helps
Most leave decisions are made in a few minutes and forgotten. The ones that go wrong are the refusals made without checking the award, directions to take leave that ignore the notice rules, and cancellations of approved leave without a basis.
A lawyer is useful at three points:
- Before the policy is written: drafting leave clauses and a refusal process that line up with the applicable award or agreement, including notice periods, peak-period rules and how competing requests are resolved.
- Before the refusal or direction is issued: testing whether a proposed refusal, excessive-accrual direction or shutdown direction is defensible, and whether the award actually supports it.
- After a dispute starts: responding to a Fair Work Commission application or an FWO investigation, and negotiating a resolution before it becomes a formal claim.
The assessment is usually quick: what does the award say, what is the operational impact, and is the decision consistent? That is exactly the sort of question a lawyer can answer in a short consultation, with the paperwork in place to prove the decision if it is ever challenged.
The Refusal That Costs the Most
The most expensive refusal is the one that cannot be explained. Reasonableness under s 88 is judged on what you can show, not on what you meant, and the two refusals that hurt employers most are the one made without a written, dated reason tied to a specific operational impact, and the direction to take leave issued without reading the award's notice rules. Both are preventable at the planning stage. Checking your award's leave clauses and your refusal process before the busy season, and getting a quick legal review of any direction or shutdown you are not sure about, costs a fraction of a general protections application or an FWO investigation. If you are facing a request you do not want to approve, start from the operational impact, write it down, and check the award before you say no.
