I'm a big believer in the theory of employees reaping what they sow.
From my seat, I found Piedmont management to be fair, respectful and interested in preserving employee dignity. And I speak from my own experience through what was an extremely unpleasant and personal FMLA-covered ordeal for me that ultimately led to my decision to resign.
I suspect that if I'd been a thorn in my boss's side, rather than an asset to my department (in spite of my personal problems), management's reaction could have justifiably been very different. I think a lot of employees forget about that basic "reap what you sow" principle.
Oh, and as a footnote, during this same ordeal, several people and several entire departments within Mainline treated me like a leper and a felon - neither of which I am or ever was.
Everyone's situation is different, and I'm glad, Jet and Harry, that you've both found Mainline better to deal with than Piedmont. Best of luck to you.
