Whether chargesheeted officer is entiteled to got all the relevent documents and case files

I (shashi kumar meena) am an employee of Life Insurance Corporation of India in the cader of Administrative officer and held a post of Zonal Vice President departments Welfare Association. I have raised some issues against some of the corrupt nature officers. management issued me a charge sheet on three trivial charges as (1) officer order, not followed (2) not participate in Branch Managing Committee (3) online DOPA (ACR) not file in time. Department conducts all the proceedings just to prove me guilty they violate all the natural and justice rules and finally gave me a penalty "REMOVE FROM SERVICE" after the interference of the National Commission for Scheduled Tribe(NCST) corporation reconsider the case and re-state me with reduced penalties. Sir I have asked to concern to give me attested copies of all the papers, documents of my case but they did not consider my request. Let me know that whether the delinquent employee has a right to know all about his own case. Let me guide what I have to do ???
