Service Book should be opened at the earliest opportunity by the Head of Office whenever an employee joins. It is also binding upon him to provide a duplicate copy duly attested by him to the employee.
In addition to that the HM, in case of a High School, has to certify that SERVICE BOOKS OF ALL THE STAFF ARE MAINTAINED PROPERLY & UP TO DATE ENTRIES HAVE BEEN MADE THEREIN in the salary requirement every month.
But Mr. VIVEK you need not worry, the service book can be prepared and made up to date in a day or two whenever it is necessary.
