I joined a private company based in Gurgaon in February 2020. I was informed of a 30-day notice period during the training period for confirmed employees and 15 days for unconfirmed employees. However, no documentation or policy was shared with me during my tenure. Later, I decided to move forward and tendered my resignation with a notice period of 17 days, assuming a 30-day notice period. Now, the company is asking me to serve a 60-day notice period as per company policy (which was never communicated to me) or a recovery letter will be issued accordingly. I need your help on how to handle this situation if any legal letter is issued to me.
