If taking a ham sandwich from the company really torques some of you guys off that much, I have to ask: why did you pick a career in which you're essentially interchangeable with about fifteen thousand (perhaps more) other people who have the exact same qualifications as you?
We're all as interchangeable as EFIS tubes or any other installed part. That's why we have numbers. If you can't deal with that fact, go do something that demonstrates you really are special, something nobody else can do, like throw a 97 mph fastball or win a major golf tournament or invent something really great. Then you can ride in the back of the plane and eat brie and caviar until you hurl.
If you CAN'T do that, accept the reality of where and what you are, take pride in your work and don't expect ANYONE to be grateful. And if they are, hey, that's just gravy.
Meanwhile, quit yer bitchin.
