As such, there is no sacrosanct guideline to be followed. However, it is advisable to invite names of the "negotiation team" from unions, which ideally should be restricted to 2-4 members. From the Management side, we should also form a "team/committee" including representation from operations, maintenance, finance, and HR. No other members than these agreed members should be allowed to participate in the negotiation. Each meeting should be minuted, and all data/information shared should be documented.
