You put in 12 to 14 hours a day at the office and often work on weekends and at home. Some people have joked that you are a "workaholic," and a few people close to you have even said that it's a serious problem. Is it? How can you tell? Chances are you're a workaholic if you feel compelled to work for the sake of working, and you feel panic, anxiety or a sense of loss when you aren't working. The workaholic is "addicted to incessant activity," said Diane Fassel, author of "Working Ourselves to Death" and chief executive of Newmeasures, which conducts employee satisfaction surveys. The behavior continues even if the worker is told that it is personally harmful - even harmful to the quality of the work, Fassel said.
