Of course, periodical increment in salary can not be claimed by an employee as a matter of right in the absence of any explicit or implied term in the contract of employment or service regulations of the organization. At the same time, when the practice of increment is in vogue, it can not be denied to an otherwise qualified employee just because he is in the process of voluntary exit some time after the prospective date of sanction of an instalment of his periodical increment for the simple reasons that increment is based on the performance in the previous year only and the employee is to get it only as long as he is in the service of the organization. Just because an employee is under notice period his responsibility to work does not get diluted and therefore he is entitled to all the due benefits of employment including his increment during his notice period also.
