It appears that your company does not have any policy in dealing with absenteeism. It is advisable to frame policy or to follow the procedure, if any laid down in the contract of service. However, keeping in view the brief details furnished by you about the case, I can say that you can send a communication in writing asking the absenting employee to report for duty specifying a date by which he should resume duty. On his resumption of duty, ask him to explain his un-authorised absence.If his explanation is not satisfactory, inform him so and warn him not to repeat this behaviour in future, failing which he will render himself for disciplinary action. If he does not report for duty,send him another letter advising him to resume work immediately. If he is still absenting from duty, send him a notice that he has voluntarily abandoned his job.and thereafter send him a final notice to that effect.
