If your employer has deducted salary for sick leave without informing you, it's important to understand your rights. The Delhi Shops & Establishment Act, 1954, outlines entitlements for sick leave, especially if you've completed a certain period of employment. If you took leave without prior notification, the company may not be obligated to grant it, even with accumulated leave. However, submitting a doctor's certificate for subsequent applications may lead to consideration at the company's discretion.
