Dear Chaitra,
Firstly, let me know whether certified Standing orders are in force in your organisation?, if not what are the provisions contained in the service rules of your organisation wrt unauthorised absence from duty.
In case of applicability of the CSO, please write a letter to him mentioning his unauthorised absence from duty from a particular date, requiring him to report for duty within (4-7) days, as deemed fit,mentioning " failing which it will be deemed that you are no longer interested to serve the company and your name shall be struck off the rolls of the company. Please send a copy (per regd/speed post) on his known permanent address, send the original letter per regd/speed post on his present address, display a copy on the notice board and send a copy to the department concerned directing them to report as soon as the employee reports to them. On the expiry of the period( (4-7) days please obtain a written report from the department about the reporting or otherwise of the employee concerned and on that basis please send him a letter (per regd/speed post) quoting the earlier letter and informing him that his name has been struck off the rolls of the company in terms of the CSO--. Copies of this letter have also be sent to all concerned in the manner indicated above.
In case the CSO is not applicable in your organisation, please follow the rules/procedure laid down for the purpose.
Thanks and regards
