I have worked with great people at Delta through ALPA, some probably for the TA and many who were part of the ..."6500 morons..." RM mentioned.
As a captain, I would never call my FO a moron on Facebook. Its bad for his position, and likely embarassing to the MEC. Even though we are all required to have thick skin and the ability to compartmentalize, if I was berated like that in a crew lounge I would not fly with this guy. Safety would likely be compromised in that kind of tense climate. This WAS his personal page...perhaps in public he reins it in enough to be effective. But after reading his berating posts...I took offense and I do not even fly at Delta.
Good luck guys...you have led the industry for a while. Your union and company cooperation...while at times not perfect...has gotten you ahead of your peers. Outside looking in, it seems to me like the company made a gross over-reach and the majority of DeltA pilots slapped their hands away. I respect the guts to do that. Enjoy your PS in the meantime...
But for all of us in the industry, hope you can work together and around the drama. Respecting each other should help. Good luck and Godspeed.
