This study seeks to understand the relationship between subjective well-being and job satisfaction among Peruvian millennials, in addition to determining the influence of components of subjective well-being, such as work-life balance, opportunity to demonstrate abilities, socialization, and possibility of learning. This study is based on the results of a questionnaire, which included questions to measure the different variables, applied to more than 300 workers in companies in Lima, Peru, from the commercial, industrial, and service sectors. The results indicate a close relationship between job satisfaction and subjective well-being. Because people are unique, organizations must be attentive to the needs of each worker's personal life and the effects of personal life on job satisfaction and must be willing to create balance and provide workers with time and space to resolve situations that arise in their lives.
