John Holland's theory of vocational personality and work environment is one of the most used, researched, and respected career development theories. Holland believes that a person's choice of a job is a person's expression so that the higher the compatibility between a person's personality and the job one chooses, the higher the level of job satisfaction and stability. But the current reality is that there are individuals who are not given the opportunity to choose and consider experience in their careers, so it is important to introduce Holland's theory to individuals who will prepare to enter the world of work by providing guidance to individuals to understand their personality, the work environment they will be they face and how the two things are related, so that individual career choices are more focused. The method used in this article is a literature review by collecting various reference sources starting from 2018-2022 related to Holland's theory. Holland's theory allows individuals to direct themselves to careers that are in accordance with one's motivation, knowledge, personality, and abilities so that it is expected to reduce problems that have a tendency to arise due to individual incompatibility with work. Therefore, it is important for counselors to be able to understand Holland's theory in order to direct individuals to a career that suits them.
