A strike authorization vote is the first step towards a potential strike, but it does not necessarily mean a strike will occur. Every union has its own rules associated with a strike authorization vote. For example, IATSE members in each impacted Local must vote by at least 75% of the participating membership to authorize a strike. If the strike authorization vote is passed, it permits the elected leadership of the union to call a strike when necessary. If that occurs, all union members will cease work and contact their local union for picket duty assignments.
