WWE and AEW could be losing workers
It has been noted that if an IATSE strike were to happen, many unions, including the men and women that film WWE and AEW will no longer be working starting this Monday, Oct. 18th. Additionally, other union members, like the lighting department, will stand in solidarity with those strike, per their contract and moral standpoints.
It is to be noted that the members of SAG, WGA, DGA and Teamsters will also stand in solidarity. That indicates no actors, writers, directors, or drivers will be working during the strike. WWE, AEW, and any other American Wrestling promotion that uses IATSE union crew will be forced to either find replacement crews or shut down production. They can potentially still run house show-style Monday Night Raws, but even that remains a huge concern.
