Career is a term defined by the Oxford English Dictionary as an individual's "course or progress through life (or a distinct portion of life)". It usually is considered to pertain to remunerative work (and sometimes also formal education).
A career is traditionally seen as a course of successive situations that make up a person's worklife. One can have a sporting career or a musical career without being a professional athlete or musician, but most frequently "career" in the 20th century referenced the series of jobs or positions by which one earned one's money. It tended to look only at the past.
As the idea of personal choice and self direction picks up in the 21st century, aided by the power of the Internet and the increased acceptance of people having multiple kinds of work, the idea of a career is shifting from a closed set of achievements, like a chronological résumé of past jobs, to a defined set of pursuits looking forward. In its broadest sense, career refers to an individual’s work and life roles over their lifespan.

Manual labour (or manual labor) is physical work done with the hands, especially in an unskilled job such as fruit and vegetable picking, road building, or any other field where the work may be considered physically arduous, and which has as a profitable objective, usually the production of goods.(...)

Beginning with the Industrial Revolution, though, the introduction of reliable machinery further lowered the status of labourers. The reduction in status led to the worldwide labour movements of the 19th and early 20th centuries, leading to the formation of trade unions. Further technological progress leads to an increasing segment of manual labour (generally using machinery) requiring more training or even theoretical insight.

A job is a role served by a person or thing, usually involving productive work. 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 favors or is trained for a certain type of job, they may have an occupation. The series of jobs a person holds in their life is their career.
