Bad bosses contaminate the workplace. Some do so obliviously, while others smugly manipulate their employees, using them as instruments of their own success. Regardless of their methods, bad bosses cause irrevocable damage to their companies and employees by hindering performance and creating unnecessary stress.
The stress your boss causes is bad for your health. Multiple studies have found that working for a bad boss increases your chance of having a heart attack by as much as 50%.
Even more troubling is the number of bad bosses out there. Gallup research found that 60% of government workers are miserable because of bad bosses. In another study 69% of US workers compared bosses with too much power to toddlers with too much power.
