Labor unions, directory of labor union sites and departments of unions and labor federations.
Sites for specific unions do not normally belong here but should instead go either to the appropriate category under Society/Work/Labor_Movement/Unions/By_Region/... or, if a US or Canadian union to either Regional/North_America/United_States/Society_and_Culture/Labor/ or Regional/North_America/Canada/Society_and_Culture/Labor/ for further filing.
