Will they keep their jobs or lose them? What have they gained if they demand more than their performance was worth?
Conversely, if someone says, "A low wage is enough for me, I don't need that much." What happens to their performance? Is it recognized by them? Will it be recognized by others? Can they extend it and gain additional customers? Or is their performance less in demand because they reduce it by demanding less than it is worth?
It depends on the proper balance of giving and taking. The reward with which we pay someone appropriately for what they have done for us motivates them to continue to serve us in the future. The balance and compensation of giving and taking carry and sustain a relationship. Where the balance is missing, we lose something.
