I am not sure whether I agree with this. Technically, it may be correct that a person continues to earn benefits while on the payroll. However, we seem to forget that all employment is a contract, and a contract contains within it certain commitments, privileges, and benefits. When the time for separation comes, we are working towards the satisfactory conclusion of a contract. The notice period is the time for the conclusion of one's commitments. As such, the period of concluding one's responsibilities should not attract a benefit other than the stipulated salary, as it is incumbent in the contract to discharge one's commitment.
