For the record, any FO posting here and complaining about DEC's knew full well what the policy was when they joined.
They will also, no doubt, be the first in the line should a better DEC opportunity present itself. Perhaps they will decline opportunities where they deem the advertising airline has "no need for perceived experience".
I'm not a proponent of the DEC policy either, but I do find it rather droll to hear the same old drivel about those nasty DEC's when the plantiff was fully aware of the incumbent policy.
One for the DEC's, could we cut the complaints about the rostering. Catching the long snake to the bottom of the rung was also a known quantity. Fortunately you have a rotating bid system.
