Frogman,
If people indeed honestly filled the survey out as you've suggested, how many do you think will actually say that "they are unhappy" AND "they are looking to leave". Definitely not those ex-A scalers who didn't sign RA65 and still have yet to leave, nor the ones that did sign over and hoping they could save up enough in the next couple years before their ex-wives take it all, nor the B scalers who are still banking on getting their 25 yrs housing, nor the C scalers born and bred in HK and know nothing about the outside World, nor the supposedly expat C scalers who still haven't got enough hours to go anywhere.
You'd be lucky to get 10% of the voting body to actually say they wanna leave, if even, especially now that they've told you each person has his/her own unique login. And because of your plea, the company gets to say "we know you guys are unhappy but not that many want to leave the BEST employer in HK, that pretty much sums it up for everyone working in Kitty City except for those of us reaping huge bonuses, so until your group actually tells us otherwise with their feet instead of their big mouths, take this crap offer and shut up in that dark little corner!"
