[2] In Canada, official data on scale and success of union raids is limited to the Federal government and the province of British Columbia.
Many union locals were effectively voting on which faction of the split "United Electric Workers" they wanted to affiliate with.
[4] Raiding by the AFL affiliated Teamsters union was such a serious issue that it prompted the trade union centers AFL,[note 1] and CIO, who had attempted to sign a no-raid agreement for years, to finally negotiate and implement such a pact in December 1953.
[12][13][14][15] Shortly thereafter, the AFL adopted Article 20 of its constitution, which forbade its member unions from raiding one another.
Since 1992, the AFL–CIO constitution has contained a clause inside Article XX forbidding union raids among its affiliates with various remedies for resolving inter-union conflict.
