Dear Mr. Sudhir, Chennai.
First Things First
The charge-sheeted employee, suspended pending inquiry, has to defend himself/herself. The role of his/her co-worker or his/her union's office bearer is to assist the charge-sheeted employee during ongoing inquiry proceedings conducted by either the Inquiry Officer or the Inquiry Committee, as the case may be, duly appointed by the Employer/Disciplining Authority (Management). This is for the purpose of conducting a domestic/internal/departmental/managerial inquiry in accordance with the principles of natural justice as well as the procedures prescribed/laid down for such internal inquiries.
It is a settled legal position that in such domestic/departmental inquiries, the appointed Inquiry Officer or the Inquiry Committee allows either a legally-trained person (advocate/lawyer) unless the Employer/Punishing Authority associates with the inquiry proceedings a lawyer/pleader, etc., or an outsider who is not the co-worker of the charge-sheeted employee/delinquent employee nor outside the concerned establishment's registered union ought to be associated.
This Kritarth Team of Inquiry Officers has practiced the aforesaid for decades without any deviation or disagreement.
