"Students, teachers and administrators, like most individuals in our soceity, are concerned about matters of basic fairness. We all know of teachers who barely do the minimum on their jobs. They often arrive late, give few tests, never volunteer for anything, leave promptly as the end of the school day, avoid all the meetings they can, and delegate their work to others. Imagine the chagrin of young, new teachers who work long hours, go the extra mile to help students after school, prepare hard for each class, and assist with extra curricular activities when they find tat their malingering colleague is making twice the salary and doing half the work.
This basic unfairness in the workplace is what some theorists (Greenberg, 1993; Tyler, 1994; Folger, 2005) call an inequity, and it brings us to yet another perspective on motivation called equity theory, which focuses on perceived fairness - individual's belief about whether they are being treated fairly or not."
