Tips
Apply early for planned leave, and check your leave balance and policy first.
For sick leave or emergencies, call or message your manager early on the first day, then send your application.
No need to share medical details. Just say you're unwell unless your company requires a certificate.
To ask for an extension, send it before your leave ends and only fill in the extra days.
Mention a colleague who can handle urgent work. It helps with approval.
If there's an HR portal or leave system, apply there too. This letter doesn't replace it.

Frequently Asked Questions
How can I write a leave application?
Address it to your manager, mention the leave type, dates, days, a short reason, and who covers urgent tasks. Sign it with your name and job title.
Do I need to give a reason for leave?
A brief reason is standard. For personal leave, "to attend to some personal matters" works, and for sick leave details of the illness aren't needed.
Is it okay to send a leave application by email?
Yes. Most employers accept email leave requests. In emergencies, inform via call or message first and follow up with an email.
How are casual leave and sick leave different?
Casual leave covers short personal needs and is usually planned. Sick leave is for illness. Check your leave policy, as details differ by employer.
