 All SBTA members but the Plumbers were in favor of admitting the Gas and Steam Fitters; all SBTA members but the Iron Workers were in favor of admitting the Lathers.When locals of the Bricklayers, Electrical Workers and Plasterers unions refused to approve their respective unions' membership in the Alliance, these international unions were forced to withdraw from the group.The remaining SBTA members immediately voted to admit the five specialty unions, a move which then led the Iron Workers to withdraw.
