I doubt images like that help the pilot's case very much because it adds weight to the idea that this is a coordinated work action. As previous cases have proved, it doesn't matter if the union is directing or involved in a work action. The courts view the unions as responsible for the actions of its members. Federal courts in RLA cases have very little tolerance for illegal labor work actions esp in a federal district court located in an area of the country that is generally hostile to labor like Texas.
