Sick leave application, including for fever, is used by employees who fall ill and cannot work. In India, companies typically offer sick leave after an employee has completed a certain period of service. There is no standardized sick leave quota mandated by labor laws; instead, companies set their own policies. Since sickness is unpredictable, sick leave application for office one day cannot be submitted in advance. When applying for sick or medical leave, check your company’s specific requirements. Some companies allow 2-3 days of sick leave without a medical certificate but require one for longer absences, while others may need a medical certificate from the first day.
The Employees’ State Insurance Scheme (ESIC) provides essential coverage for sickness, maternity, disability, and work-related fatalities. Employees who are insured can access medical services and receive 70% of their wages during periods of sick leave.
Women facing health issues related to pregnancy or those who experience a miscarriage are entitled to a month of medical leave. With appropriate documentation, they can receive wages under the maternity benefit scheme, as outlined in Sections 6 or 9 of the Act.
Organizations have varying approaches to managing unused sick leave:
Pros: This policy can promote the accumulation of leave for serious health issues or planned pregnancies, which may enhance employee retention.
Cons: It might result in a surge of absences at year-end or encourage employees to come to work while unwell, potentially spreading illness. A more limited carry-forward policy tends to be more effective.
Some companies may provide payouts for unused sick leave upon an employee’s resignation or termination. Any policy regarding payouts should be consistent and free from discrimination.

Be clear about how long you’ll be off work. Include both the start and end dates.

Let them know that you’ll provide any required documents like a medical certificate, as per company policy.
