Feeling stressed out by project deadlines? You\u2019re not alone. Two recent surveys of business executives and senior managers have outlined and evaluated the top 20 causes of work-related stress. Two groups of 300 CIOs, CEOs and other executives surveyed by the Net Future Institute in January said deadlines are the number-one cause of personal and interpersonal office anxiety. Other big stress inducers include budget constraints, coworker conflicts and job security (or lack thereof)."Deadlines are ubiquitous," explains Chuck Martin, chairman and CEO of the Institute, a North Hampton, N.H.-based think tank that identifies and analyzes business management and IT trends. "Nearly every executive at every level of every organization deals with them."According to Martin, some survey participants said a certain level of stress in the office can be a positive motivating factor, as it keeps people alert. On the other hand, too much stress can be debilitating.Respondents also listed e-mail overload, performance expectations, poor organizational communication, political stress and the impact of layoffs as some of the other factors that raise their stress level. Bad lighting and other environmental issues, as well as pressure from direct reports, caused the least amount of workplace anxiety.
