I may add, MoU/agreement(s) are signed, in many instances, a tripartite document involving, 1) management representatives, 2) Representatives of either all recognised unions or elected union representing all employees), and 3) Labour Commissioner-in-charge of the area or duly appointed under conciliatary machanism. It could be on wages revision or other allowances, perquisites and all other service conditions. Once the MoU/ agreements are executed by all parties there is no possibility of any secrecy. Moreover such documents should be placed on the notice board of the estt. and if no copy is available Conciliation office can provide copies when asked for.
