How to Maintain Service Book?

Service Book is an essential part of the documents of a employee. It is the soul of all the service of an employee. Every major activity or event related to service of an employee is entered here in the service book. It goes throughout all the service of a non-gazetted employee. It is necessary that there must be made two copies of the service book. 1st copy must be in the custody of the head of the office and the other be handed over to the individual. The individual should refresh the service after every year or at the time of his/her transfer.
