I don't mean to diminish the achievement of the CC banding together with some semblance of solidarity. Truly. Kudos to them.
But if one is rational - and honest - it's far easier to be "brave" when you have far less, or nearly nothing, to lose. (Which is why people fitting that description are far more dangerous, as well.)
The average profile of cabin crew at EK: young, single, few years invested in the company, and no designs on a career there; is nothing like that of the average profile of a pilot at EK: older, often with a family to support, and highly invested in their career. (This demographic is shifting by EK design to favour pilots fitting in the former profile, I know!)
This is a generalization and of course there are many exceptions in both groups. And again, this is NOT intended to disrespect those cabin crew who DO have a great deal to lose and showed up anyway.
But as such, especially given the vastly larger employee group, it is perfectly logical that a "revolt" should gather far larger numbers of cabin crew than pilots. Good old Harry though, never missing a chance to disparage his colleagues as lacking "balls"...do you need a link to the definition of "patronizing" or what...?
