Also,think about the alternative possibitity if you don't like your job this mean that you will reduce your performance? Maybe up to a certain point,but there will be factors that prevent you from reducing your performance:the fear of getting fired,the desire to get a promotion so that you can get out of job that you dislike so much, or your professional work ethic.as a result, we should not expect a one-to-one relationship between satisfaction and performance. Still,the observed correlation between work attitudes and performance is important and has practical value.
