Job satisfaction, employee satisfaction or work satisfaction is a measure of workers' contentedness with their job, whether they like the job or individual aspects or facets of jobs, such as nature of work or supervision. Job satisfaction can be measured in cognitive (evaluative), affective (or emotional), and behavioral components. Researchers have also noted that job satisfaction measures vary in the extent to which they measure feelings about the job (affective job satisfaction). or cognitions about the job (cognitive job satisfaction). One of the most widely used definitions in organizational research is that of Edwin A. Locke (1976), who defines job satisfaction as "a pleasurable or positive emotional state resulting from the appraisal of one's job or job experiences" (p. 1304). Others have defined it as simply how content an individual is with their job; whether they like the job. It is assessed at both the global level (whether the individual is satisfied with the job overall), or at the facet level (whether the individual is satisfied with different aspects of the job). Spector (1997) lists 14 common facets: appreciation, communication, coworkers, fringe benefits, Job conditions, nature of the work, organization, personal growth, policies and procedures, promotion opportunities, recognition, security, and supervision. Evaluation Hulin and Judge (2003) have noted that job satisfaction includes multidimensional psychological responses to an individual's job, and that these personal responses have cognitive (evaluative), affective (or emotional), and behavioral components. Job satisfaction scales vary in the extent to which they assess the affective feelings about the job or the cognitive assessment of the job. Affective job satisfaction is a subjective construct representing an emotional feeling individuals have about their job. Hence, affective job satisfaction for individuals reflects the degree of pleasure or happiness their job in general induces. Cognitive job satisfaction is a more objective and logical evaluation of various facets of a job. Cognitive job satisfaction can be unidimensional if it comprises evaluation of just one facet of a job, such as pay or maternity leave, or multidimensional if two or more than two facets of a job are simultaneously evaluated. Cognitive job satisfaction does not assess the degree of pleasure or happiness that arises from specific job facets, but rather gauges the extent to which those job facets are judged by the job holder to be satisfactory in comparison with objectives they themselves set or with other jobs. While cognitive job satisfaction might help to
