Adecco's 'Where-the-Jobs-Are' Report Shows Increased Hiring on Long Island.

MELVILLE, N.Y. -- In advance of the New York state unemployment report, Adecco (NYSE:ADO), the staffing industry's market leader in the U.S. and the world, today announced it is seeing increased demand for employees throughout Long Island, especially in the financial services and recruiting industries. The Long Island area is one of the many locales across the country where Adecco is responding to a growing need for contingent workers from employers in a variety of industries.

Lori Farley-Toth, Adecco area vice president for Long Island, says, "We are still seeing high demand in financial services for the three A's: accountants, analysts and auditors." In a nod to the improving Long Island job market, Farley-Toth added, "HR positions are booming. Many companies are hiring recruiters right now for both temporary and permanent workers. I think as we came out of the recession, companies started seeing their customer base pick up and they had no time to train, so they turned to staffing firms and recruiters to find exact job matches in a hurry. Now they are adding internal resources in the next step toward growth."

Farley-Toth adds, "Job seekers should take note that in addition to traditional temporary hiring, Adecco branches are receiving more requests for direct hire candidates. In addition, many people on long-term temporary assignments are being hired full time by the client." People to fill temp-to-hire administrative assistant and data entry positions in a wide variety of industries, including mortgage brokering, the manufacture of business products and personal care products, and distribution centers, are in high demand from companies on Long Island.

Farley-Toth notes, "This has been a great year for temporary staffing so far. According to the Bureau of Labor Statistics, the nation's temporary staffing industry grew 6.9% from April 2004 to April 2005. Adecco is seeing similar percentage growth in the number of associates we're placing on Long Island."

Adecco releases its "Where the Jobs Are" report in advance of the state unemployment reports to provide more depth and breadth to the employment picture in selected regions. The report is based on interviews with Adecco recruiters across the country and consists of press releases that report on hiring trends in regions experiencing employment growth. The trends in these regions are not intended to be indicators of nationwide trends.
