With unemployment still high, it would make sense that only the best and the brightest would be working - but dysfunctional employees abound. IT's not that these so-called professionals don't have the skills they need to do their jobs, whether they're networking experts or mobile app developers. They're not dummies. However, they can have some serious personality problems that no one picked up on during the interview process. In his book "Flip the Script: How to Turn the Tables and Win in Business and Life" (Free Press/available in May), author Bill Wackermann pinpoints these classic personality types that get in the way of your department's success. He also offers approaches that CIOs and other managers can consider to help their wayward employees become team players. Wackermann is executive president and publishing director at Conde Nast.
