Notice period issue

Without knowing the terms and conditions of the employment, any advise or opinion rendered woould be a misguidance. 

Moreover it is not known that what transpired between you and the principal in the intermittent period, hence you may revert with the details or background facts or you can consult an advocate in the local in order to proceed further  legally or to do away with it.

What is the verbal communication between?  Without facts, a proper opinion cannot be formed.

Verbal communication has no legal value, show your appointment letter to a local prudent lawyer for proper appreciation and professional advise.

Even otherwise, notice period is maximum 3 months (generally), which is upto o8th March 2026, for that either you may surrender salary for remaining period or continue to serve

The meaning of notice period on the part of an employer means that if he intends to terminate an employee he should give notice of say x months. After giving notice of x months either he can retain him for x months and terminate him at the end of the period or he can terminate him immediately giving him salary of x months in lieu of service.

If employee wants to resign he has give notice of x months and serve for x months if so required by employer. But the employer can terminate his service at any time within the notice period. He is not bound to give salary beyond date of actual termination. So your employer has to keep you in employment and pay salary up to December 31st only. This is the normal practice.

You may bring the verbal discussions to the notice of HR and seek furhter instructions.
