NEW YORK—From New York to LA to Chicago and beyond, it’s time to build out flexible work models. So says ManpowerGroup. Virtual offices could play a key role in those flexible work models.

Manpower points to a report from the U.S. Bureau of Labor Statistics that the overall August jobless rate dipped to 8.1 percent. The U.S. private sector added 96,000 new jobs last month, while summer jobs figures were revised down, and from 64,000 to 45,000 in June to 163,000 to 141,000 in July.

"Flexible work models—which include temporary, part-time, full-time and virtual workers—remain the best option for an economy beset by wildly fluctuating demand," says Jeffrey Joerres, chairman and CEO of ManpowerGroup. "U.S. employers face extreme uncertainty from what's happening in the Euro Area and with the U.S. general election two months away, yet demand exists and employers continue to need the right workers at the right time to meet that demand.

According to ManpowerGroup's 2012 Talent Shortage Survey results, 49% of U.S. employers struggle to fill mission-critical positions. Skilled trades, engineering and IT positions continue to place on this list year after year. New York virtual offices could help New York employers win more talent. Virtual offices tend to be an attractive feature for employees looking for flexible work.

"A flexible work model that enables companies to react quickly to demand and that aligns with companies' business strategies is essential for winning in today's volatile economy," says Joerres. "In turn, individuals benefit from flexible work options, as they gain on-the-job training and experience—while earning income."

Virtual offices are part and parcel of a flexible work strategy, whether it’s virtual offices in New York, virtual offices in LA, or virtual offices in some other city. With the rising demand for flexible work, virtual office space should become even more popular among the modern workforce.
