The document discusses job satisfaction, including its definition, factors that influence it, and models for measuring it. Job satisfaction is defined as a positive feeling about one's job resulting from an evaluation of its characteristics. Two major theories discussed are Herzberg's two-factor theory, which identifies motivators and hygiene factors, and Hackman and Oldham's job characteristics model regarding core job dimensions. Common measurement methods include Likert scales and indices that assess satisfaction with factors like pay, supervision, and work itself.
