Job evaluation provides a systematic basis for determining the relative worth of jobs within an organization based on factors like the importance of the job, skills and qualifications needed, and difficulty level. There are analytical and non-analytical methods for evaluation, such as ranking, classification, and point methods. Wages refer to payments for blue-collar work, salaries to white-collar work, and compensation includes wages and benefits. Minimum wages provide for basic sustenance while living wages provide for needs and insurance. Various laws regulate wages and benefits in India.
