There are many reasons to sign up with a temp agency. You might need supplemental income, you might work while you look for job, or maybe you want to get your foot in the door at a top company. Whatever your reason for signing with a temp agency, you can count on plenty of assignments to choose from once you become a member of the temp talent pool.

According to a recent Los Angeles Times article, many temp agencies report that business has been on the rise since around September of 2010 and according to the American Staffing Association, the number of temporary workers jumped 25%, to an average of 2.6 million a day, in the third quarter of 2010 compared with the same period a year earlier. One Torrance, CA staffing agency owner even stated that sales on the temporary-employment side of her business, which accounts for about 70% of her revenue, were up 8% in 2010 compared with the year before. So why all the interest in temporary workers?

Agencies that provide temporary staffing are benefiting from the fact that companies are feeling more optimistic about their short-term prospects but not confident enough to add permanent workers.

“The new reality is people have been much more resistant to bringing on permanent employees than they have been in the past because of the uncertainty of where the economy is going,” said Michael Neidle, president of Optimal Management, a San Mateo, Calif., consulting firm for small- and medium-size staffing companies.

Neidle estimated that temporary workers would make up 4% of the workforce within three years, from a low of 1.65% before the recession.
