Temping

Advantages

You get to investigate the inner workings of various companies before you accept a permanent job.
If you don't like the company, the work, or your supervisor, you're free to leave at any time.
The pay can be excellent--$15-20/hour and more, depending on your skills and the market, with regular increases.
Temporary positions can lead to permanent job offers.
You can pick up valuable on-the-job skills while looking for that "perfect job."
You can meet people who might help you network to find a full-time, permanent position.
The hours and days are flexible.

You may be treated as an inferior worker because you're "just a temp."
You may not get clear direction or much attention from managers.You probably won't receive insurance or other health benefits, though some temp agencies will provide benefits for long-term employees. You may have to drive to different offices and report to different supervisors each day.
Just as you learn the system, your assignment (and job) may end.
You might get stuck doing nothing but answering phones or filing.
Professional relationships are difficult to build if you're constantly moving on to the next job.
