2. Accident: "I was involved in a minor accident this morning and require rest and treatment."
3. Urgent Travel: "I need to take emergency leave due to an unforeseen personal obligation requiring immediate travel."

For emergency leave requests, update your manager immediately and ensure proper task delegation. Emergency leave requests are more effective through email and direct communication.
