Absolutely!
Just another thought about the key word catering: it seems very common practice to upload 0 catering for the crew and leave them with the leftover catering the clients did not care to eat. The argument is: why?, we pay you SNTs for that! Well many times you land when the shops are already closed or there are simply no shops close by to be reached. If you are unlucky you might be able to scavenge a handful leftover rice, a bit of the gravy sauce and a few leftover grapes for desert - and share it with the other two colleagues on board. And that after you've paid for all your education and training and possibly your SSTR.
Unless we put our foot down and say NO - they will continue to treat us like a bunch of rats. I know there are of course companies that differ.
