It's challenging to find great information technology (IT) employees, but keeping them may be even harder, new research from Robert Half Technology suggests. Although most chief information officers (CIOs) recently surveyed (72 percent) rate their workers' satisfaction levels fairly high, more than one-third (35 percent) of IT workers polled said they plan to look for another job in the next year, and another 35 percent are unsure about whether they'll stay. Chief contributing factors to IT workers' search for greener pastures are the need for new challenges and a lack of career advancement potential.
