Medical Certificates for ESI-Covered Employees
In respect of employees covered under ESI, the employer is making his contribution to the ESI. As such, the employee cannot say that he consulted a private physician and his medical certificate should be taken as a supporting document. Instead, he is expected to produce a medical certificate from ESI only. If the company has a medical officer, then the certificate from that medical officer can only be considered valid.
Exceptional Cases for Private Medical Certificates
In exceptional cases, where the employee was on leave (other than medical leave), was out of station, and fell sick during the leave period, seeking an extension of leave on medical grounds, he can use the medical certificate from a private doctor as a supporting document. Simply put, for ESI-covered employees, a medical certificate from a private medical officer can be used as a supporting document but not as proof of medical or sick leave.
