FYI, just some facts. (Since facts seem to be something you like to play fast and loose with.)
The Hat's off switch on ALAP's web site is not a job action. Sorry to inform you that the lawyers have thoroughly reviewed this one before it was implemented many months ago.
Additionally it is a strong statement of unity. (Another concept you may not be familiar with.) Just like wearing an ALPA pin became a signal of unity before and after ALPA's successful strike against UAL in 1985. Since then the pin is something every member wears as part of his uniform. Only "non members" aka "scabs" do not wear it. At United, a slick tie (one without an ALPA pin) is a like a Scarlet Letter indicating a pilot who crossed the picket line in 1985.
Fact # 3 is that this hat's on/off program has gotten the attention of management and is a thorn in their side. When 8000 pilots wear their hat religiously one day, and suddenly take it off the next at the direction of our MEC Chairman, it sends a clear signal to management that we are marching in unison and are behind our leadership, and our unity can not be broken. It also demonstrates that our communication system from union leaders right down to the line pilots is operating efficiently. Pilots are instructed to carry their hats at all times, and if approached by management in public view and asked to wear the hat, to comply.
I know that being a USAir pilot, it is hard to see the real advantages of unity, coming from a group as fractured as yours. However life outside of USAir works much differently than on other properties. (Thankfully.)
This instance of a pilot removing himself from a flight due to emotional distress is not directly related to any ALPA initiative. ALPA encourages all pilots to self-assess their ability to operate safely at all times and are fully supported by the union in doing so. IMO this pilot did the right thing, because had it not been for this particular confrontation, it would have been something else that pushed him over the edge.
