What to do with a toxic employee

In order to avoid the negative consequences of having toxic employees, the company proceeds with trial hires (usually 6 months).
The purpose of this is to terminate the contract once the period is completed and not to pay any kind of compensation to the new worker.

Also, carrying out rotation of personnel to try to find the best task and function for each employee, or carrying out regular assessments and surveys to help identify toxic employees.

It is common for at first they appear to be the most productive employees and manage to deceive. The collaboration of the staff and the attentive gaze of the managers are essential to be able to point out the toxic worker that will eventually create crisis situations in the medium and long term.

When the above fails, you should try to give a chance for them to reconsider and improve their behavior. Regular meetings may serve with a clear and natural dialogue.

They are used to correctly analyze and evaluate the toxic employee and to be able to make the appropriate decision. If even then the bad situation in the company does not improve, firing is the most suitable.

How to manage toxic employees?

The best leaders are able to trust their instincts, but they also know how to rely on other sources of information. If you have doubts about an employee, do not be afraid to ask for help.

Even if you’re not sure if someone is toxic or not, it’s always good practice to be wary of anyone who makes you feel uncomfortable. If something doesn’t feel right at work, take the necessary time to find out why.

As a manager, it’s important not only to know when to intervene and how to manage toxic people, but also that your team trusts you enough to do so.

Behavior of toxic employees

Toxic behavior does not always manifest as major explosions. They’re more likely to be small infringements that accumulate over time, which is why it’s valuable to document them.

You’ll need this information if you ever decide to take disciplinary action against an employee for their toxic behavior.

But even if you never have to use what you’ve documented, there are other reasons to keep a record.

Think about it: if an employee has been acting toxic for years and nobody has ever mentioned it (to them or to anyone), that means it was probably an accepted part of your culture.

Once something is accepted as normal, it can be hard for people to see anything wrong with it. That’s why documenting toxic behaviors can help reinforce company values.
