All crew members should band together and not bother to respond to the survey.
Do the survey as many others will (last time 700) and this will determine what the proposal is. At least if you have done the survey you can let them know plenty of what you don't like. As far as Q25, you have to pick an answer but copy it into the comments box and tell them that it wasn't a good choice. The data from many of the other questions will tell them that crew don't want what they are proposing. Q4 no, Q5 no, Q6 (a), Q24 (c) are some such questions.
