Nowadays many adults have full-time jobs and the proportion of their lives spent doing such jobs is very high. So feelings about one's job must reflect how an individual feels about his or her life as a whole, and because of this, job satisfaction is indeed very important to the well-being of that person. Employees get job satisfaction in a number of ways. Firstly, a person needs to feel that they are doing valued and valuable work, so positive feedback from superiors is very important in this respect. A sense of fulfillment is also encouraged if a worker feels the job is worth doing because it contributes to the society or the economy as a whole. Secondly, when some feels they are improving or developing their skills through training opportunities, for example, then there is a sense of progression and purpose that rewards a worker. The sense of belonging to a team or a working community also contributes to job satisfaction because colleagues help each other to enjoy their working lives. Satisfaction is also increased by a sense of responsibility for and loyalty to a team.
