Dear Prabhu Ji, the law of the land is binding on us, and we must comply with it. A termination order does contain the reasons for termination. Therefore, if it is prudently drafted with necessary details about one's total services, incorporating the date of commencement of services, no separate service certificate is necessary.
Service Certificate Considerations
Generally, a service certificate is considered a recommendatory reference. Therefore, in the case of dismissal, no special service certificate should be issued separately without quoting reasons for dismissal. I do agree with you that absconding is not a major crime or an illegal act. However, I am not inclined to support it. If an employee is not satisfied with his job, he must tender resignation, bid goodbye, and part with it instead of taking recourse to absconding from duty.
