How to Address Toxic Behavior in a High Performer

Is it worth it to put up with a high performer that is toxic?

Having an extremely high-performing “rockstar” employee who consistently exceeds expectations is a key asset to a team's success. However, what happens when these top performers have bad attitudes? Regardless of their great contributions, their difficult behavior can be detrimental to the team’s morale and create friction. For managers, the challenge is balancing the value of these influential team members while also fostering a positive workplace culture.

While an employee may be a ‘high performer’, poor behavior constitutes underperformance in their role and can lead to more significant negative effects on the rest of the team. Over time, other team members may question why this poor behavior is tolerated and cause resentment towards management for failing to address such attitudes. Overall, the high performance of an individual can outweigh their positive contributions to the team, ultimately providing a net negative impact on the organization as a whole. 

Problems that can arise from a negative team member include: 
  • Other team members may not want to work closely with the negative team member.  
  • Team members may not feel comfortable sharing their opinions and providing feedback during group discussions. 
  • The firm may experience higher employee turnover, and other good employees may leave due to frustration.  
  • Decreased team performance due to a negative environment and reduced collaboration. 

Given the large implications a negative employee can have on a team, it’s important to navigate these challenges appropriately. Approaching the situation without a presumption of malintent is a critical component to ensuring the employee doesn’t develop a defensive attitude, ultimately hindering a productive conversation. The toxic team member may not be aware of their poor attitude and the implications of their actions on the team as a whole. Facilitating an open and honest discussion about their attitude and strategies to improve is crucial to productively addressing concerns. 

Here are some strategies for navigating this conversation and devising an improvement plan: 

1. Focus on Specifics & Identify Underlying Cause
When initiating a conversation about a poor attitude it is important to focus on the specific problem at hand. Similar to a performance review, identify specific instances in which they ‘underperformed’ and avoid generalizations. Not referencing specific examples may not properly communicate what needs to be adjusted. 

If the poor behavior is a more recent development, see if there is an underlying source for this negative mindset. The team member might be experiencing challenges in their personal or professional life that are causing them to take out their frustrations on the team. Make sure to actively listen to the challenges they are facing and be prepared to help workshop solutions to any difficulties they have within the workplace. Team members are more likely to communicate concerns if they believe management will take their feedback into consideration and work towards solutions. 

2. Set Clear Expectations for Improvement
After identifying the problem, setting clear expectations for further improvement and how adjustments to their attitude will have a positive impact on the team. Not only will a good attitude improve their performance, but will create a more positive workplace culture. Outline specific behavioral expectations including maintaining respect, collaborating with peers, and fostering a positive work environment. 

When communicating expectations, emphasize they are non-negotiable aspects of their role and are imperative to future success within the firm. By establishing that performance isn’t solely measured based on contributions but also by their attitude and interactions, managers can effectively set the tone for acceptable behavior. Overall, setting clear expectations provides a structure of behavior accountability while also recognizing the employee’s contributions. 

3. Create an Effective Action Plan 
Collaborate on an action plan with specific steps they can take to improve their attitude. This communicates the importance of making changes and provides actionable implementation steps. Within this action plan, discuss strategies to shift their negative behavior to more positive alternatives such as productive outlets.

Negative behavior can often manifest due to frustrations that the toxic team member has with others on their team. Providing them with a productive outlet for negativity can work to redirect their emotions to positive solutions. An example of a productive outlet may be creating solutions for a team member who consistently voices frustrations to communicate their concerns directly with management.

Even with strategies in mind, it can be difficult to determine the best ways to handle a toxic team member. Discussing solutions with human resources can help gain an additional perspective on the situation and provide insights on alternative solutions with the firm. Other resources such as horizontal mentorship groups can give leaders a community to discuss these challenges and hear how other leaders handled similar situations. 

In addition to reaching out for support, proactively addressing poor behavior is a key preventative measure to reduce negative behavior in the workplace. Address concerning behavior immediately when it occurs or soon after to prevent continued issues. Waiting for individuals to adjust their behavior on their own accord often doesn’t work and allows for the negativity to continue. Furthermore, proactively addressing problems communicates that this behavior isn’t tolerated on the team nor within the firm, regardless of an employee's output. 

Proactively addressing poor behavior may also manifest through creating mechanisms for team members to share concerning experiences with other team members. Ensure all team members feel comfortable reporting behavioral issues and have the correct resources to communicate such concerns. 

While high performers may create a lot of value on a team, if they create a toxic environment they may be doing more harm than good. Addressing the problem and providing opportunities for growth gives them a chance to reflect on their behavior and make changes. However, if a team member is unable to adjust their attitude, consider alternative solutions including removal from the team. Even if a team member is a ‘rockstar’, they aren’t worth compromising the team as a whole.
