Profit-sharing is most definitely not pay. We should focus on surpassing AA's payrates.
Profit-sharing is a useful tool in motivating employees by allowing them to share in the success of the enterprise. It's a bonus that can come and easily go.
So what if it's "at risk?" Keep it "at risk" and concentrate on the payrates.
So what if AA doesn't want their employees to share in the success? That's evidence of their management's lack of vision.
