This is what you should think about when voting - according to a very pro yes member at another forum:
- IMPOSITION - what will this bring in the future?
- Inexperienced volunteers being drummed up to do YOUR job.
- The current terrorist threat level increase from SUBSTANTIAL to SEVERE (an attack is highly likely)
- Medical emergencies onboard the aircraft.
The ONLY thing to think about when voting is about the imposition - nothing self - but go ahead and tell crew otherwise - it's only to your own disadvantage.
