It used to be like this in South West Airlines, everybody was expected to lend a hand if he had nothing more important to do, so if an engineer or pilot had nothing to do in his own job, he would toss luggage, if a hostie had a few idle hours on the ground, she would help out with the check-in crew.
But they all saw the result on their bank account at the end of the year, since the company would pay a percentage of their profits to the staff as a bonus.
Don't know though if it still works like this.
