Every Effort Has Value
You are correct, the employees and judgment-holders must avail themselves of every possible avenue to exert pressure. Alone, none might matter but as the crescendo builds, it will have an effect: pilots preferring to accept competing job offers, lessors and aircraft owners preferring not to entrust their asset to Prestige Jet.
And don't underestimate the value of the embarrassment to Hamed Al Hamed for tolerating and supporting this travesty, which is becoming an embarrassment to the government of Abu Dhabi, which has foolishly given it "government company" standing.
