Practice As most people spend a major part of their adult life at work, job satisfaction is an important element of individual wellbeing. What factors contribute to job satisfaction? How realistic is the expectation of job satisfaction for all workers? In present days, companies become the primary units in the commercial activities, and people in companies spent quite a part of their lifetime at work. As a result, work satisfaction becomes more and more important for individuals. In my view, there are material and mental factors that contribute to job satisfaction. Firstly,The development of modern industry force more and more people move into metropolises, and most men and women are now depended on working for organizations, works make money for people, and people buy what they need with money in their city life. So, a better pay can improve job satisfaction, that is why a good pay position is always have more applicants. The second factor can be mental when a basic demand for living is reached or workers can not find a job to earn more money. There are many elements influence job satisfaction,such as environments, work pressures, colleagues,etc., and above all, people tend to choose a promising occupation. Consequently, companies shall communicate with employees constantly to improve working environment, and to make sure that employees regard their jobs as a meaningful job which they are willing to do. However, it is unrealistic to have all worker satisfied their work. One reason is a company's financial conditions. The more money employers spend for employees, the more cost for a company. The other reason is that the workers' productivities must be considered, so promotions can only be provided to a few people, and workers' characters can be various, which means there is not any measures can satisfy all workers. In conclusion, I believe people shall choose their working in their own will may be much satisfy with their job, and a well-form human resources market can help employees find their suitable job.
