Provide an effective forum, perhaps some kind of pilot council (non-management/non-union), where pilots concerns can be aired in strict confidence (no video/audio) without fear of retribution. A forum organised by pilots for pilots where the views given can then be presented to management in a constructive, more diplomatic manner; the results of which are presented back to the pilots.
There is no reason why Emirates cannot have a private forum here at Pprune, as many other airlines do, if one or two of you can be persuaded to moderate it for the benefit of all of you (and not to use it as a stage for your own views!).
