This document discusses factors that influence job satisfaction, including organizational factors and personal factors. It cites research showing that happier employees are 12% more productive and companies that invest more in employee satisfaction see productivity increases. When employees feel their interests are supported by the company, they are more likely to be committed, loyal, and go above and beyond their duties. Job satisfaction is influenced by achievement, responsibilities, advancement, and personal growth. Satisfied employees are less likely to quit and are considered "marathon runners" rather than "sprinters."
