Jobs from WikiPedia:

A job is a regular activity performed in exchange for payment, usually as one's occupation. A person usually begins a job by becoming an employee, volunteering, or starting a business. 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). 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.

Most people spend a good portion of their waking time doing a regular job. Exceptions are if you are a student or retired.

Jobs come in great variety: full time jobs, part time jobs, temporary work, odd jobs, summer jobs, self-employment

People may have a chosen occupation for which they have received training or a degree.

Someone may pursue a vocation but support themselves financially with a day job. Those who do not hold down a steady job may do odd jobs or be unemployed.
