As a flight attendant for a legacy carrier, can't imagine what whistle is being blown. While the lual and lcal flight attendants are still separate working on a joint contract that is not exactly a state secret.
As a pilot there, I can vouch that there are no secret rules or working conditions needing a whistle.
