IB,
Fair enough, you may not know what they are going through on a daily basis, and to individually judge someone is probably tough to do unless you are very familiar with their job. However you can judge the product that GF is supplying and those managers are responsible for that product.
If the product is up to speed then likely the management team is doing their jobs. If the product is subpar then they are lacking somewhere, and i can see why an employee would be frustrated with the situation.
One other point. You think it was the managers that got you a 30% pay rise? I'm not sure i can see a group of the local managers fighting for a pilot pay rise. I suspect it has alot more to do with the large group of pilots that resigned forcing a decision to be made that worked to retain some amount of experience before it was all gone.
Best of luck to all those who remain with GF..hope to see your house in order sooner rather than later.
