Which social-psychological perspective best explains Janet's change in attitude and behavior after getting promoted to a management position?

Jean's best friend, Janet, recently got promoted to a management position in the company where they both work. The new job is associated with more pay and prestige. Jean notices that Janet is spending more of her time, on and off the job, with her friends in management. Over dinner, Janet confides in Jean that she is really perturbed by the poor behavior of her former coworkers, that they have bad attitudes on the job, and that she doesn't know how to handle them now that she is their supervisor. Jean and Janet continue to be friends but they don't interact as much at work any more.
