Dear member,
I 've no idea as to which state's Shops & Estt Act applies to your estt. But 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 Tamilnadu- I am not sure) or the Factories Act,1948 except in the event of termination of the services of the employee.Moreover, the the maximum no of days of such leave that can be accumulated is limited to 24 in the former(in Tamilnadu) 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 or 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.Better arrive at a bilateral settlement in this regard u/s 18(1) of the I.D Act,1947.
