A person's
job is their role in society. A job is an activity, often regular and often performed in exchange for
payment. Many people have multiple jobs, such as those of parent, homemaker, and employee. A person can begin a job by becoming an
employee,
volunteering, starting a
business, or becoming a
parent. The duration of a job may range from an hour (in the case of odd jobs) to a
lifetime (in the case of some
judges). The activity that requires a person's mental or physical effort is
work (as in "a day's work"). If a person is trained for a certain type of job, they may have a
profession. The series of jobs a person holds in their life is their
career.
