I have no idea as to which state's Shops & Estt Act applies to your establishment. However, I am sure that annual encashment of Privilege Leave or Leave with Wages in lieu of avail has not been provided for either in the State's Shops & Estt. Act (other than Tamil Nadu - I am not sure) or the Factories Act, 1948 except in the event of termination of the employee's services. Moreover, the maximum number of days of such leave that can be accumulated is limited to 24 in the former (in Tamil Nadu) and 30 in the latter. However, by virtue of the operation of the provisions of Sec.78 of the Factories Act, better terms in this regard under any other law or award, settlement, or contract of employment are permissible. Periodical or annual encashment of such leave can be considered more beneficial to both the employer and the employees. It is advisable to arrive at a bilateral settlement in this regard under Section 18(1) of the Industrial Disputes Act, 1947.
