Nine percent of chief information officers (CIOs) plan to expand their information technology departments during the second quarter of 2011, and 2 percent expect to cut jobs. Based on a telephone survey of more than 1,400 CIOs from a random sample of U.S. companies with 100 or more employees, the quarterly IT Hiring Index and Skills Report by Robert Half Technology found that 80 percent of CIOs are confident in their companies’ growth potential during the next three months, and 73 percent of technology executives are at least somewhat optimistic that their organizations will invest in IT projects in second quarter. According to survey respondents, security and networking professionals are in greatest demand right now.
