Can My Boss Refuse My Annual Leave? When They Can (and Can't)

Under the National Employment Standards, full-time employees accrue 4 weeks of paid annual leave per year (5 weeks for certain shift workers). Part-timers get it on a pro-rata basis. That leave is yours — you've earned it.

But your employer doesn't have to approve every leave request the moment you ask. They can refuse if they have reasonable business grounds — things like critical deadlines, staff shortages during peak periods, or a major project that needs your involvement.

What they can't do is refuse every single request indefinitely, refuse without any reason, or use the refusal to punish you. The key word here is "unreasonable." Under section 88 of the Fair Work Act, your employer must not unreasonably refuse a request to take annual leave.

If your leave keeps getting knocked back with vague excuses or no explanation at all, that's likely unreasonable — and you've got options.

There's no exhaustive list in the legislation, but the Fair Work Commission and Fair Work Ombudsman have given guidance on what might be reasonable grounds for refusing a leave request:

• Other staff are already on leave during the same period and your absence would leave the team unable to operate
• It's a critical business period — end-of-financial-year for accountants, Christmas for retail, harvest season for agriculture
• A major project or deadline requires your specific involvement and can't be rescheduled
• Insufficient notice — requesting three weeks off starting tomorrow isn't giving your employer a fair go to plan around it

What's not reasonable: "We're always busy," "I just don't want to approve it," or "Nobody takes leave during their first year." These aren't genuine business grounds — they're just gatekeeping.

Your employer also needs to consider alternatives. Could they approve part of the leave? Could they approve different dates? Could someone cover your duties? If they haven't considered any of these before refusing, their refusal starts looking unreasonable.

Here's a twist most people don't know about: if you've accumulated too much annual leave, your employer can actually direct you to take some of it.

Under most modern awards, annual leave is considered "excessive" when you've accrued more than 8 weeks (or 10 weeks for a shift worker). When that happens, your employer can give you a written direction to take leave — but there are rules:

• They must confer with you first and try to reach agreement on when you'll take the leave
• The direction must be reasonable
• The direction must not result in your leave balance dropping below 6 weeks
• They must give you at least 8 weeks' notice (under most awards) before the leave starts
• The leave period must be at least 1 week

So if you've been hoarding leave for years and you've got 12 weeks banked up, your employer can ask you to take some — but they can't empty your balance. And they have to work with you on the timing.

On the flip side, if your leave balance is excessive because your employer keeps refusing your requests, that's on them — and it actually strengthens your position to push for approval.

Some workplaces close down during certain periods — most commonly over Christmas and New Year. If your employer has a shutdown provision in the applicable award or enterprise agreement, they can direct you to take annual leave during the shutdown.

Most awards allow employers to direct employees to take leave during a shutdown, provided they give at least 28 days' written notice. If you don't have enough accrued leave to cover the shutdown period, different awards handle it differently — some allow you to take unpaid leave for the shortfall, others let you go into negative leave.

If your workplace doesn't have a shutdown provision in the award or EA, your employer can't just unilaterally declare a shutdown and force you to use your leave. They'd need to reach agreement with affected employees or negotiate an enterprise agreement that includes shutdown provisions.

Check your award or EA before the shutdown is announced so you know where you stand. If your employer is directing you to take leave during a shutdown, make sure they've given proper notice and that there's actually an award provision backing it up.

Casuals don't accrue annual leave. That's one of the trade-offs for the 25% casual loading that's meant to compensate for the lack of leave entitlements, job security, and other benefits permanent employees get.

If you're a casual and you want time off, you don't need to request "leave" — you simply make yourself unavailable. Your employer doesn't have to give you shifts, but equally, you don't have to accept every shift offered. There's no formal leave approval process because there's no leave to approve.

However, if you're a casual who's been working regular and systematic hours and your employer starts cutting your shifts because you asked for time off, that could be adverse action under the Fair Work Act. Casuals have protections too — they just work differently.

If you're a casual who's been working like a permanent employee (same days, same hours, every week for months or years), you might actually be entitled to convert to permanent employment under the casual conversion provisions in the NES. Once you convert, annual leave starts accruing. Something to think about.

If your boss has refused your annual leave and you reckon it's unreasonable, don't just stew on it. Here's your play:

1. Ask for the reason in writing. A verbal "no" is harder to challenge. Email your boss: "Can you please confirm in writing the business reason for refusing my leave request for [dates]?" This puts them on the spot and creates a paper trail.

2. Propose alternative dates. Show you're being flexible. "If those dates don't work, I'm also available to take leave on [alternative dates]. Can we find something that works?"

3. Escalate internally. If your direct manager is the problem, go to their manager or HR. Sometimes a leave refusal is one person being difficult, not company policy.

4. Check your leave balance. If you've got excessive leave accrued (8+ weeks), point that out. Your employer has a legal interest in you taking leave, and continued refusals look worse when your balance is sky-high. Use our leave entitlements tool to check your balance.

5. Contact the Fair Work Ombudsman. If internal avenues haven't worked, call 13 13 94 or visit fairwork.gov.au. The FWO can help you understand your rights and, if necessary, intervene.

6. Apply to the Fair Work Commission. If there's a genuine dispute about whether the refusal is reasonable, you can apply to the FWC under the dispute resolution provisions of your award or EA. The FWC can mediate, conciliate, or — if needed — arbitrate and make a binding decision.

Your annual leave is an entitlement, not a favour. You earned it. Don't let anyone make you feel bad for wanting to use it.
