A good result
Voluntary voting often has turnouts of 50% or so. If you assume most of the survey respondents were AOA members then we probably had 60-70% completing.
Who normally responds to surveys? The extremes -people who feel strongly one way or the other. The middle of the road group often (rightly) feel that their input will not affect the outcome. Just because we don't have 100% responding doesn't mean we won't have meaningful data from the survey. With correct statistical sampling you can get fairly accurate results from just a couple of percent of the population. Because in this survey you are self selecting, you need a bigger sample to make it relevant.
So ask yourself what the other 1200+ pilots think. Is every non member or AOA non replier happy here? If so, why wouldn't some of them have wanted to say so? The truth is that many are middle of the road or, worse still, so despondent and apathetic they have lost the will to effect change...the last attitude I see more and more of - three of my friends have left CX in the last 3 months!
We had almost 900 pilots fill out a survey out of 2300 pilots - CX got almost 100 responses out of 20,000 employees last month with its campaign of "WeSuggest" - which leadership has greater issues????? (trick question - same leadership;-)
