Re read it. If your flight is canceled during an IROP, you as a line holder must sit Airport standby for up to 4 hours. After your 4 hour sit THE PILOT must make positive contact with CS in order to be released.

On hold for 2 more hours? Better not go home or you are subject to disciplinary action. This kind of crap is littered throughout the TA if you actually read it and stop letting B6ALPA sell you a bill of goods.
