As a manager, you may one day face a situation that feels uncomfortable, emotional, or even intimidating: an employee whose behavior suggests a possible substance use issue. You might notice changes in performance, attendance problems, safety concerns, or behavior that feels out of character. Knowing what to do—and what not to do—matters for the employee, the team, and the organization.
This guide walks through two common scenarios:
- When an employee appears to have a substance use issue but has not disclosed it
- When an employee admits they have an addiction and wants to seek treatment
In both cases, thoughtful leadership, consistency, and partnership with HR and legal are essential.
First: Focus on Performance and Safety, Not Assumptions
Managers should never diagnose or label an employee. Even if the signs feel obvious, substance use is a medical issue—and assumptions can quickly lead to legal risk.
What you can do:
- Address specific, observable behaviors (e.g., missed deadlines, safety violations, attendance issues)
- Apply the same performance standards you would to any employee
- Document facts, not interpretations or rumors
What to avoid:
- Accusations (“You seem drunk”)
- Asking about medical conditions or substance use
- Gossiping or involving others unnecessarily
If safety is at risk, follow your organization’s established safety protocols immediately.
How to Handle a Performance Conversation
When issues arise, keep the conversation professional and behavior-based:
- Describe what you’ve observed (dates, incidents, impact on work)
- Clarify expectations and consequences
- Ask if there’s anything the employee needs to be successful at work
This creates space for disclosure without pressuring the employee to share medical information.
If the Employee Admits They Have an Addiction and Want Treatment
This is a critical moment—and one where the Americans with Disabilities Act (ADA) may apply.
Under the ADA:
- Past or current addiction can be considered a disability
- Employees who seek treatment or recovery support may be entitled to reasonable accommodations
- Employees are not protected for misconduct or performance issues that violate policy—but they are protected from discrimination based on disability
What managers should do immediately:
- Thank the employee for being honest and acknowledge the courage it takes to speak up
- Do not promise outcomes (such as job protection or specific accommodations)
- Pause the conversation and involve HR right away
At this point, HR (and potentially legal counsel) should guide next steps, including:
- The interactive accommodation process
- Leave options (FMLA, ADA leave, company policies)
- Documentation requirements
- How to balance accommodations with essential job functions
Why HR and Legal Partnership Is Non-Negotiable
Substance use, disability law, privacy, and workplace safety intersect in complex ways. Managers should never handle these situations alone.
HR and legal can help ensure:
- ADA compliance
- Consistent application of policies
- Proper documentation
- Protection of employee confidentiality
- Reduced legal risk for the organization
Involving them early protects everyone—the employee, the manager, and the business.
Supporting Recovery While Maintaining Standards
Supporting an employee through treatment or recovery does not mean lowering expectations indefinitely.
Managers should:
- Continue to hold employees accountable to essential job duties
- Follow agreed-upon accommodations consistently
- Communicate clearly and compassionately
- Monitor performance based on work outcomes—not assumptions about recovery
Compassion and accountability can—and should—coexist.

Final Thought for Leaders
How you respond in these moments sends a powerful message—not just to one employee, but to your entire team. Leading with professionalism, empathy, and legal awareness builds trust while protecting the organization.
You don’t have to have all the answers. You just have to know when—and how—to involve the right partners.
