When toxic employees' negative behaviors are tolerated, it can have a hugely detrimental effect on the company's culture, decrease collaboration between teams, affect how customers are treated, and so much more.
People in leadership positions will often look for a quick fix, but it’s not that simple. It’s easy to blame the hiring process or one individual employee, but unfortunately, the buck stops with you because you are the person who sits in the leadership position. You need to take full responsibility for your department's or organization's low morale and urgently address the situation before all the good employees leave and the toxic remains.
One must remember, if you want the perks of leadership, you must pay the price of leadership.
