Joe's new manager Martha has heard about Joe's star performer status. However, she has seen only average performance from him. In a face-to-face meeting with Joe, she finds out that his old manager used to reward Joe's hard work with more work. Bonuses were usually not linked to performance. Moreover, Joe would have really appreciated rewards like some extra time off and a flexible schedule so that he could take care of his elderly parents. His previous manager always promised those rewards but never actually gave them. Suggest how Martha can motivate Joe in light of the expectancy theory.
