I have been working at a private IT company and willing to pay in lieu of the notice period of one month and one month of service. In the appointment letter, they mentioned the need for a two-month notice or payment of gross salary for two months. However, in CiteHr, many articles mention that the payment in lieu of notice will be based on the basic salary. Can you please help me find the correct way? Do I pay the gross salary or the basic salary?
