and all
CRM was started at UAL because they kept crashing planes because one person was wrong and someone else was right, but the person in charge was wrong and there was no recourse.
SO, now a days, GIVEN TIME (plenty of time sitting on the ground in san francisco) ANYONE who brings up a safety concern must (according to CRM) have their say and have things made right.
The Airline did have the "RIGHT" to relieve the crew and have a new set of FA's come work the flight. BUT the FA's had the right to believe things were ok and they simply were not.
Now, many years ago, those little drawings only meant the airline was no good at keeping their planes washed...but now a days...well its different.
IF IT WERE THE GOOD OLD DAYS they would not have been delayed...but in the good old days I could ask anyone to sit in the jumpseat or come to the cockpit in flight.
Good old days only work one way, not both ways.
They do have a good legal case, they have brought suit and will likely win or settle. And now their union has demanded their reinstatement.
