Employment history refers to a record of a person's previous jobs, including details such as job titles, companies worked for, and the duration of employment. This information is often included in a resume or CV to provide potential employers with insight into a candidate's work experience and skills. Having a clear employment history is important for job applications, as it helps employers assess a candidate's qualifications and suitability for a position. It can also highlight career progression and relevant experiences that may contribute to success in a new role.
