Dear member,
What is happening with you is unfortunate. Sometimes we have to face a mix of unfavorable events as well as unfavorable actions from seniors. Anyway, do not lose your spirit.
I recommend you prepare a handwritten application for leave. In this application, write down when you were infected with COVID-19, what kind of treatment you are taking, etc. If you are able to take a printout, then attach a copy of the medical report that shows you are COVID-19 positive. Send the letter by Speed Post to your company. Later, scan the copy of the letter along with the receipt from the post office and send the application to HR. Write to them that you had approached your HOD; however, you are yet to receive approval for the leave, hence the application. If you do not receive a reply from HR, then send one more letter to the MD of the company. However, do not rush to send the application to the MD. Wait for 3-4 days since you sent the first application to HR. I hope you get a positive reply from the MD.
General Comments: Across India, the second wave of COVID-19 is on the rise. Against this backdrop, if an employee is in distress due to a COVID-19 infection, HR is supposed to stand by the employee. As a representative of the employees, they should take up the work on behalf of the employee. However, if HR remains inactive, then it is very unfortunate.
Thanks,
