Multiple unionism leads to multiple enrolment in unions and no subscribing members, causing delay or failure to get recognition. This restrains a union’s bargaining power during a period of prolonged strife while the unions are squabbling among themselves for dominance, the workers are deprived of their wages and the plant suffers a loss of production. Multiple unionism qualitatively weakens the movement resulting in the formation of small- sized unions without effective organization.

However it must be noted that in spite of foregoing there are many organizations where multiple unions exist and the management does effectively negotiate, and conclude agreements. In many plants, workers are unionized –on a craft basis –their special skills or training bonding them together. Multi-unionism is more a problem where general unions exist, for whom all categories can be organized in one general union.
