Manage a high-performing employee’s inappropriate workplace behavior by addressing it promptly, identifying specific conduct and expectations, gathering the relevant facts, and applying your policies consistently to similarly situated employees. Depending on the seriousness of the conduct and your policy, the response may range from coaching to formal discipline or termination. Document the process and consult HR or employment counsel when legal risks may be involved.
Key Takeaways
- Address specific conduct promptly rather than relying on labels such as “bad attitude” or “toxic.”
- Verify the facts and give the employee an opportunity to respond before deciding on discipline.
- Apply lawful behavior standards consistently to similarly situated employees, while considering severity, history, and mitigating circumstances.
- Before discipline, screen for protected complaints, concerted activity, leave, accommodation needs, and other legal protections.
- Use coaching, a written warning, a performance improvement plan, or another response appropriate to the issue. Not every case requires the same progressive steps.
- Document facts, expectations, support offered, the employee’s response, and the legitimate reason for the decision.
- Involve HR or employment counsel before high-risk discipline or termination.
Why Behavior Problems Are Worth Addressing Early
It is tempting to look the other way when your most productive employee is also difficult, but unaddressed behavior problems can wear on a team over time. In iHire’s December 2024 survey of 1,781 workers, 53.7% reported having left a job because they considered the workplace toxic, and 58.9% said they would accept lower pay to leave a toxic workplace. The survey reflects self-reported experiences from iHire’s job-seeker database and does not establish that a specific employee caused turnover.
The effects of unaddressed conduct may not show up on a single line of your financial statements. They may emerge gradually through coworker disengagement, increased conflict, or a perception that results excuse inappropriate behavior. If turnover or engagement problems are increasing, review the broader workplace environment, including leadership, workloads, communication, fairness, and unresolved interpersonal conflict, rather than assuming one employee is the sole cause. In iHire’s own findings, the leading contributors to perceived toxicity were poor leadership, poor communication, unfair treatment, and burnout.
Verify the Facts Before Deciding on Discipline
Before deciding that discipline is appropriate, gather the relevant facts. Identify the policy or workplace expectation at issue, review available records, speak with appropriate witnesses, and give the employee an opportunity to respond. Consider whether the concern reflects misconduct, a performance problem, a communication difference, a workplace conflict, or an unclear expectation.
For complaints involving harassment, discrimination, retaliation, safety, violence, or other serious allegations, use an impartial investigation process and involve HR or employment counsel promptly. Fact-finding helps prevent conclusions based solely on an unverified complaint.
Share information only with those who need it to evaluate or respond to the concern, and do not promise complete confidentiality when a fair investigation may require disclosure. Remind everyone involved that retaliation is prohibited, preserve relevant records, and consider interim measures when necessary to protect employees or workplace safety. Interim measures should not be punitive or unnecessarily burden the person who raised the concern.
Don’t Let It Slide
When an employee’s behavior falls short of your workplace standards, address it rather than waiting for it to change on its own. Treating high performers differently sends a message to the rest of your team that standards bend for productivity. Use the same workplace standards and evaluate similarly situated employees consistently, the way you would handle disciplinary action for anyone else in a comparable situation.
Comparable cases should generally receive comparable treatment, but differences in severity, prior discipline, role, evidence, mitigating facts, and applicable agreements may support different outcomes. Document the legitimate reason for any material difference so the basis for the decisions is clear.
Have a Conversation, and Focus on Behaviors
An employee is not likely to change if nobody addresses the behavior directly with them. As a leader, meet with the employee and be specific about which identified behaviors failed to meet a stated workplace expectation and how they are affecting the team, rather than simply telling them they have “a bad attitude.” “Attitude” is an inference, not something you can point to. Naming specific behaviors, like repeatedly interrupting colleagues in meetings, missing stated deadlines without providing required notice, or making comments that violate an identified respectful-workplace standard, gives the employee a clear opportunity to understand and respond. When you document the conversation, capture the employee’s actual words, the date, context, any witnesses, and the applicable expectation where relevant.
If the behavior changed suddenly, give the employee an opportunity to explain whether there is relevant context or support the employer should consider. A manager might ask, “Is there anything affecting your ability to meet these expectations, or any support you would like us to consider?” Avoid pressing for a diagnosis or unnecessary personal or medical details. If the employee raises a possible disability, medical condition, pregnancy-related limitation, religious issue, protected leave need, or request for accommodation, involve HR before finalizing the response. An accommodation request does not necessarily excuse past misconduct, but it may trigger obligations concerning leave, the interactive process, or support that will help the employee meet expectations going forward.
Before You Discipline, Check for Legal Considerations
Before disciplining, determine whether the conduct is connected to protected activity. An employee’s criticism, complaints, or discussions with coworkers may be legally protected depending on the subject, context, and manner, for example, reporting discrimination, harassment, wage-and-hour concerns, safety issues, or other suspected unlawful conduct; requesting leave or an accommodation; participating in an investigation; or discussing wages and working conditions with coworkers. Protected activity does not excuse independent misconduct, but discipline must be based on legitimate, nonretaliatory reasons and supported by evidence that the same standards would have applied absent the protected activity. Do not characterize an employee’s complaint, participation in an investigation, accommodation request, or protected discussion of working conditions as a behavior problem merely because it is critical, uncomfortable, or disruptive to management.
If the employee is represented by a union, review the collective bargaining agreement and any applicable representation rights before conducting an investigatory interview or imposing discipline.
Employers may generally hold employees with disabilities to job-related conduct standards that are consistent with business necessity and applied to all employees. However, if an employee requests an accommodation or provides information suggesting one may be needed, involve HR promptly. A reasonable accommodation may be required to help the employee meet expectations going forward. Medical information should be requested only when legally permitted and maintained confidentially in a separate medical file.
What If the Behavior Doesn’t Improve?
If coaching does not produce improvement, the next step may be a written warning, a performance improvement plan (PIP), or another measure permitted by your policy. The document should identify the specific behavior, the relevant expectation or policy, prior discussions, required improvement, available support, a reasonable review period when appropriate, and possible consequences. Accurate documentation may help demonstrate that later decisions were based on legitimate, consistently applied expectations, but it does not eliminate legal risk.
A PIP is not always appropriate for misconduct. Serious harassment, threats, violence, dishonesty, or safety violations may require an investigation, interim protective measures, or more immediate discipline.
Give the employee an opportunity to respond and record the response fairly. If a warning requires a signature, clarify that the signature acknowledges receipt, not necessarily agreement. If the employee declines to sign, document that the warning was presented and that the employee declined to acknowledge receipt. A witness may be appropriate under your organization’s policy or circumstances. Maintain disciplinary records consistently in accordance with your organization’s retention policy and applicable law. Restrict access to those with a business need, and keep medical or accommodation information in a separate confidential file. Clear, contemporaneous records may be relevant in later administrative proceedings or litigation, but outcomes depend on the facts and applicable law, and unemployment standards vary by state and often differ from the standard for a lawful termination.
Take Preventive Measures
Catching behavior problems before they take hold helps the whole team stay productive. Keep communication channels open so employees feel comfortable reporting problems, and coach your supervisors on how to recognize and respond to behavior issues early, rather than waiting until a pattern is well established. Supervisors are often the first to notice a shift in someone’s behavior, so equipping them to act on it matters as much as any policy on paper.
This is also where hiring practices come full circle. Define job-related behavior expectations, such as respectful communication, collaboration, reliability, and compliance with safety rules, and evaluate candidates and employees using structured, consistently applied criteria. Avoid vague “culture fit” judgments that may conceal bias or disadvantage candidates with different communication styles or backgrounds.
When Should You Let a High Performer Go?
At some point, if the behavior does not change and your process has run its course, keeping an employee whose conduct harms the team can cost more than a departure would. If the facts support the concern, the employee has received any process required by policy or agreement, and coaching or an opportunity to improve was appropriate under the circumstances, termination may become a reasonable option. Serious misconduct may warrant a different response.
It helps to ask a direct question: if this person’s performance were average instead of exceptional, would you have already addressed this the same way? If the answer is yes, strong performance may be affecting how the organization evaluates conduct that it would otherwise address more directly. Termination can carry legal risk beyond discrimination, including retaliation, protected leave, protected concerted activity, contract, and state-specific rules, so review the evidence and consult HR or employment counsel before acting when the facts present elevated risk. The decision itself, and the legal risk that comes with it, ultimately rests with you as the employer.
Frequently Asked Questions
Should a high-performing employee be disciplined the same way as anyone else?
Hold high performers to the same behavior standards as similarly situated employees. Comparable cases should generally receive comparable treatment, but differences in severity, prior discipline, role, evidence, and mitigating facts may support different outcomes. Applying standards consistently supports fairness and helps you defend decisions later, as long as you document the legitimate reason for any material difference in how a situation is handled.
How do I address a bad attitude without it turning into a vague argument?
Focus the conversation on specific, observable behaviors rather than the label “attitude,” which is really just an inference. Instead of saying someone has a bad attitude, point to concrete actions, like interrupting coworkers, missing deadlines, or dismissive comments in meetings. Behaviors are harder to dispute than a general impression, and they give the employee something specific and actionable to work on going forward.
Can one difficult employee really affect the whole team?
Unaddressed behavior problems can wear on coworkers over time and contribute to turnover. In iHire’s December 2024 survey of 1,781 workers, 53.7% said they had left a job because they considered the workplace toxic. The survey reflects self-reported experiences and does not establish that one employee caused turnover, so review the broader environment, including leadership, workload, and fairness, rather than assuming a single cause.
What should I do if a high performer’s behavior changed suddenly?
A sudden change is often worth a direct, private conversation. Ask whether there is relevant context you should consider, such as unclear expectations or workload, and what support might help. Avoid pressing for medical or personal details. If the employee raises a possible disability, medical condition, leave need, or request for accommodation, involve HR before finalizing your response, since it may create obligations going forward even though it does not necessarily excuse past misconduct.
What comes after the first conversation if the behavior doesn’t change?
If a direct conversation does not lead to lasting improvement, the next step is typically a documented measure, such as a written warning or a performance improvement plan (PIP), consistent with your policy. Documentation creates a record of expectations and support offered, which may help demonstrate that later decisions were legitimate and consistent, though it does not eliminate legal risk. Serious misconduct may call for investigation or more immediate action.
Can I terminate a high-performing employee for behavior issues?
An employer may generally discipline or terminate an employee for legitimate, documented behavior that violates lawful workplace standards, subject to applicable law and agreements. Before termination, review the evidence, relevant policies, comparable cases, employment or collective bargaining agreements, and whether the employee recently engaged in protected activity or raised a possible leave or accommodation need. State-specific rules, including Montana’s good-cause requirements in some circumstances, may also apply. Consult HR or employment counsel when the facts present elevated risk.
How can I prevent behavior problems from spreading through my team?
Keep communication channels open so employees feel comfortable raising concerns before they escalate, and train supervisors to recognize and address behavior issues early rather than waiting for a clear pattern to form. Supervisors are usually the first to notice a shift in someone’s behavior, so equipping them to respond quickly is one of the most effective preventive steps a company can take.
Should I get HR involved before disciplining a high performer?
Involving HR or an HR partner early is generally advisable when the conduct is serious, disputed, recurring, or likely to result in formal discipline. HR involvement is especially important when the employee has raised a complaint, requested leave or accommodation, participated in protected activity, is covered by an employment or collective bargaining agreement, or may be terminated.
This article provides general human resources information and is not legal advice. Discipline and termination requirements vary by jurisdiction, employer size, policy, contract, protected activity, leave or accommodation status, and the specific facts. Employers should consult qualified HR or employment counsel before taking action in high-risk situations.
