Resigned health problem,very urgent

while fulfiling your contractual obligaiton as per  your company norms, no need to pay any amount, health ground is good ground for obtaing leave and you forced to submit your resignation  - you have legal remedies make  representation for sanction of leave on health ground, if your employer terminates you without sanctioning leave, employer has to pay compesation.        

Mr. Sekhar has given valuable advice. Kindly follow it.

It seems all transactions posted by you are verbal.

You may submit your leave application under acknowledgment. let HR decline in writing.Termination during sickness is usually treated as bad order.

If you have decided to separate you may tender notice of resignation and then submit leave application with copy of bed rest adviced by doctor. Let HR decline sick leave in writing.Company shall avoid written declinature.

If HR/line management is damant you may submit a representation in writing under acknowledgment aqddressed to good offices of your appointing authority, MD, CEO, Company Secretary, with a copy to Head-HR.

In all probabilities you shall get relief. If no relief is granted you may approach a lawyer and legal notice can get you relief.

You can withdraw your notice of resignation before effective date of resignation and you shall continue to be in employment. You can later submit a leave application again. Company should adopt a human approach in such cases as yours.
