Dear Saikumar ji,
It seems to me from the queriest post that he is 27 years old and his management engaged his services but his name is not borned on muster roll of company. He is in impression thtat he should have minimum age limit to acquire a job / service on roll of company.
I may be wrong totally in undestanding the query.
On the basis of my understanding, my answer to queriest is as under:
1. There is no system of 'off roll' as he said. All the persons employed should be kept on 'on roll'.
2. Minimum age for employment is 18 years completed.
3. Maximum age is as per standing orders applicable to him but not over 60 years of age.
4. If at all there is a system of 'off roll' is in existence in his company, it is illegal.
