Such people are contraindicated in any team. For them, not to harm means to live a day in vain. To insult, to "accidentally" blurt out, to complain about colleagues - for such toxic employees this is a normal Tuesday. They are quite dangerous, since they can spoil the psychological climate of any healthy team.
A boor and a rude person
How to recognize them?
They are always dissatisfied with someone; complaints from such employees come in a rather aggressive form.
They are quite shameless and can be rude to anyone without thinking.
They like to issue benefits of reaching overseas chinese consumers in europe ultimatums, write complaints, and threaten “higher” authorities.
How to work with such people?
If the team works harmoniously, everyone respects each other, such toxic employees may not appear at all. If such an employee appears, it is important to take action quickly. However, increasing the number of responsibilities or promotion will not help here.
Find out what the employee's problem is. Maybe this aggression has its own reasons, and by eliminating them, you will return the employee to the team.
If the employee himself is the source of this rudeness, have a personal conversation with him.
If no measures help, and colleagues continue to complain about his behavior, it is better to part with such an employee.
By the way, it is precisely such employees who can write unpleasant reviews about the companies where they worked, and even speak inappropriately about the company's management. It is not worth paying attention. Perhaps you should call your fellow managers so that they do not accidentally hire him.
Martyr
Such an employee, as he himself believes, works harder than anyone else. He gets the most difficult tasks, the management does not like him and underestimates him. The toxicity of martyrs is that they irritate other employees with their whining and endless stream of complaints about their fate. The danger is that they can convince their colleagues of injustice, undermining their faith in the bright future of the company and the competence of the manager.
Martyr
It is worth noting, by the way, that such employees can be very thoughtful and diligent.
