Hi, When the employee was asked to serve a proper notice period instead of sharing a long leave request, the employee should have discussed with HR in person with proper medical proof for a waiver of the notice period. After submitting a resignation, just leaving the employment open-ended is not the right practice on the side of the employee. In a way, it has to be construed as abandonment of service even though he had submitted a resignation. While HR has the right to initiate disciplinary action, HR may investigate and find out whether the sickness reason is genuine. If so, after collecting proper medical proof, he can be relieved, and the notice period amount can be recovered from FFS if feasible.
