In this blog, we’ll explain how to do it properly, why it matters, and how HR teams in the UAE and beyond can stay compliant. We’ll also talk about how experts like HNI—one of the leading corporate training providers in the UAE—help companies build HR systems that are fair, simple, and legal.

Why Calculating Annual Leave for Part Time Employees Matters

Let’s begin with the basics. Annual leave isn’t just a benefit—it’s a right. Every employee, full-time or part-time, should get some rest. That’s why calculating annual leave for part time employees fairly is important not only for legal compliance but also for employee morale and trust. 

But here’s the tricky part: part-time employees don’t work a standard 40-hour week. Some might work 20 hours, others just 10. That means you can’t give everyone the same number of leave days. So how do you do it?

Let’s break it down.

Understanding UAE Labour Law

In the UAE, labour law grants employees annual leave based on how long they’ve been with a company and how many hours they work. For full-time employees, the law typically provides 30 calendar days of leave per year, once they’ve completed a year of service.

For part-timers, this is adjusted proportionally. And this is where calculating annual leave for part time employees gets interesting.

Prorated Annual Leave: What It Means

“Prorated” simply means you calculate leave based on the number of hours or days the employee works. For example, if a full-time worker gets 30 days of leave per year, someone who works 50% of the hours should get 15 days.

How to Start Calculating Annual Leave for Part Time Employees

Let’s go through the step-by-step process you can use to calculate this accurately.

Step 1 – Confirm the Full-Time Entitlement

In your company, how many leave days does a full-time employee get annually? Let’s say it’s 30 days.

Step 2 – Measure the Part-Time Hours

Now, check how many hours per week the part-time employee works. If your full-time employees work 40 hours a week and your part-timer works 20, that’s 50%.

Step 3 – Do the Math

Multiply the full-time leave by the percentage the part-time employee works.

Example:

30 days × 0.5 (50%) = 15 days

So, this part-time worker gets 15 leave days per year.

It’s really that simple.

Real-Life Examples

Let’s look at a couple of practical examples to show how calculating annual leave for part time employees works in real life.

Example 1 – Flexible Schedule

Fatima works three 5-hour shifts per week, totaling 15 hours. A full-time schedule at her company is 40 hours.

Fatima’s percentage = 15 ÷ 40 = 0.375

If full-timers get 30 days of leave:

30 × 0.375 = 11.25 days

Fatima is entitled to around 11 days of leave.

Example 2 – Project-Based Role

Ahmed works 10 hours per week. His company’s full-time schedule is 40 hours.

Ahmed’s percentage = 10 ÷ 40 = 0.25

30 × 0.25 = 7.5 days

Ahmed gets 7.5 days of leave per year.

You can round the number up or down depending on your policy, but always make it clear in the employment contract.

Common Mistakes to Avoid

Even experienced HR teams make mistakes when calculating annual leave for part time employees. Here are the most common ones:

Using fixed days instead of hours: This leads to unfair results.

Ignoring service duration: Employees earn leave over time.

Applying full-time policies to part-timers: This can lead to overpayments or legal trouble.

This is where working with experts in HR consultancy in Dubai or reliable human resource consulting services can make a huge difference.

Making Things Easy with HR Tools

Modern HR software can automate this process. You input the work hours, and the system calculates the correct leave entitlement. But you must configure the system properly. That’s where human resource consulting and training companies like HNI can help.

HNI’s Role in HR Training

HNI, one of the top corporate training companies in the UAE, provides specialized training in UAE Labour Law, leave policies, payroll, and compliance. They also help HR departments implement efficient systems for calculating annual leave for part time employees, ensuring legal compliance and employee satisfaction.

What if the Employee Hasn’t Worked a Full Year?

If a part-time employee has only been with you for 6 months, you should calculate their leave on a pro-rata basis based on months worked.

So, if someone is entitled to 12 days of leave per year and they’ve worked 6 months:

12 × (6 ÷ 12) = 6 days

And if they work 20 hours in a 40-hour week:

6 × 0.5 = 3 days

They get 3 leave days.

Yes, calculating annual leave for part time employees sometimes involves a little math, but once you understand the formula, it becomes routine.

Why Getting It Right Matters

You might think, “It’s just a few days—who cares?” But this mindset can cause problems:

• Legal penalties
• Employee dissatisfaction
• High turnover
• Damaged reputation

Accurate calculating of annual leave for part time employees reflects your company’s professionalism and care. And in places like the UAE, where employment regulations are strict, this isn’t optional—it’s a must.

HR Best Practices

Here are a few tips to improve your policies:

• Always include clear leave clauses in contracts
• Document everything
• Use software to reduce human error
• Train your HR team regularly
• Work with a trusted HR consultancy in Dubai for guidance

And most importantly: respect part-time employees’ time just as much as full-time workers.

The Bottom Line

Getting annual leave right isn’t just about ticking boxes—it’s about creating a workplace where everyone feels valued. When you take care of the small details, people notice. So whether you’re a startup, a growing business, or a large enterprise, make sure you have a clear system for calculating annual leave for part time employees.
