As many as one in four US workers may be often angry on the job, and angry employees also are more likely to get bored, have low energy and feel trapped in their posts, according to a survey. Employees are most likely to be angered by a boss, or by a fellow employee in the workplace not being productive, or by tight deadlines or by heavy workloads, said Donald Gibson, a professor at the Yale University School of Management.
On the one hand, an unstable economic environment has produced productivity and growth; on the other, it has produced change and uncertainty, which has influenced the workplace negatively. According to Professor Gibson’s survey, while a majority of employees are responding to these conditions with reports of workplace satisfaction, there remain a substantial portion who are dissatisfied, even angry at work. Obviously, anger is linked to workplace aggression, which appears to be increasing: We are weekly confronted with stories of workers taking aggressive, even violent action particularly against their bosses.
 The survey found that 25 percent of those contacted said they were at least somewhat angry at work on a continuing basis. Angry employees tend to have less energy and interest in the job, and tend also to be bored. And angry employees tend to feel trapped in the job. The study did not discuss what percentage of angry workers are likely to use violence. It did find that they feel less loyal to the employer. There have been a number of workplace shootings in the United States over the years, which is really worrisome.
