Employee commitment is a critical element to increase job performance. An important predictor of teachers' commitment is motivation, which motivates employees to spend time and energy in the organization. Because of this fact, there is a growing interest in understanding the relationship between motivation and commitment. Despite plenty of research on the issues of motivation and commitment, linkages between two forms of motivation (intrinsic and extrinsic) and the three components of commitment (affective, continuous and normative) are hardly investigated.
