Union instrumentality refers to the extent to which employees believe that a union can effectively obtain positive work aspects or remove the causes of their dissatisfaction. Option A correctly states that the more employees perceive a union to be capable of obtaining positive work aspects, the more instrumental they perceive the union to be in resolving their job dissatisfaction.
