A temp job is shorthand for "temporary job". Temp jobs are useful for folks who can only work on irregular days or for limited times. While not designed as a career, some people are able to make a decent living and pay their bills by working only temp jobs.
The down side to working temp jobs is that there may be days where your skills are not needed. If you know how to take shorthand but cannot work retail, your options day by day can be limited.
Temp jobs are a good way for a company to try before you buy. If you work well with the others on your team and are proficient at your work, you may get an offer for full-time employment.
