I'm not labor attorney but I do know that such an event would be an illegal job action. So if RAH pilots did this while the IBT still practiced a policy of RLA compliance then the pilot group would be liable in a law suit by management. A sick out would be annoyance but in my opinion nothing short of a total walk-out would give them any leverage. Sick-outs will just cause a political and legal fustercluck for that PG. It would make a point but it won't hamstring management potently enough to leverage suit protection like a walk out would. The PG has to be willing to risk a permanent RAH shutdown and job loss for any stand up action that defys the RLA.
