Can two unions simultaneously submit two separate charters of demands to the management of the same company? We heard that at one pharmaceutical company, two unions have submitted separate charters of demands. Union A has submitted a COB with a reasonable hike, whereas Union B has submitted a COB with a very high hike. The management wishes to negotiate with Union A, as their demand is quite reasonable. Will it be valid? Can someone share any case laws or articles related to how the management can proceed legally?
