Bad bosses can kill you. Even more so than factors such as whether the employee smokes, exercises, or has weight problems. The data comes from a four-year-long study in Switzerland and was published in the Journal of Occupational and Environmental Medicine.
Workers who were subject to inconsiderate and uncommunicative bosses were about 60% more likely to suffer a heart attack or other life-threatening cardiac condition. Employees who had strong leaders as bosses, on the other hand, were roughly 40% less likely to suffer heart emergencies.
