The answer can be BOTH. Managers have often asked me how to deal with an employee who is disruptive (that does not necessarily mean all disrupters have a bipolar condition). Anxiety disorder has become one of the most common mental health conditions.
If you manage a large team or even a few people over a number of years, chances are you’ve encountered an employee struggling with an anxiety disorder. React well as a leader/manager and you’ll help the struggling employee recover and contribute to your organizational success. Pile onto their problem and you’ll help send that employee, and your results, into downward spiral.
