A toxic boss could affect the mental health, not to mention the career, of an employee. It is important to know to recognize a toxic boss and to properly deal with the situation.

As reported by Forbes, University of Manchester's Business School's recent study involving 1,200 participants across different industries found the negative effects of working with a toxic boss. For one, those who are working with one have low job satisfaction rates.

But the more alarming impact is the kind of person a narcissistic or psychopathic boss can create out of their subordinates. A toxic boss can influence his employees to be over critical or aggressive with one another. He can create a bully out his subordinate because of his negative attitude, and he can be a reason that an employee experiences a clinical depression.

This is a call to companies to look into how they measure leadership success. Toxic bosses could meet the short-term performance goals, but their toxicity could have a longer, more costly impact to an organization. For instance, a company might be losing some $14,000 per worker in lost productivity due to workplace incivility, Forbes added.

Those who do not listen to employees, shift the blame to others, do not guide their team well, and who always focus on the negative are leaders who are toxic to work with, according to Entrepreneur. As an employee, there are ways to deal with such bosses and not let their toxicity ruin your personality and career.
