Employer guide: Handling illness-related job performance legally

On Behalf of | Nov 3, 2025 | Employment Litigation

Running a business means balancing empathy with accountability. Sometimes, an employee’s illness or injury makes it hard for them to do their job. If that person is not covered by the Family and Medical Leave Act (FMLA) or workers’ compensation, you must handle the situation carefully. Knowing how the Americans with Disabilities Act (ADA) and Illinois law work together helps you avoid costly mistakes.

Clarifying your legal obligations

Under the ADA and the Illinois Human Rights Act (775 ILCS 5/), you must offer reasonable accommodations to qualified employees with disabilities. Still, the law will not force you to keep an employee who cannot perform the main duties of the job, even after you have tried to help.

Before you decide what to do next, follow a clear and simple plan. These steps protect your company and lower your risk:

  • Confirm the employee’s essential functions.
  • Explore possible accommodations early.
  • Document every discussion, evaluation and accommodation offered.
  • Reassess whether continued employment supports business needs.

These actions prove that you acted in good faith. If they still cannot perform their role, this record shows that your decisions are fair, data-driven and defensible. It also gives you evidence to rely on if a dispute comes up later.

When ethics meets business realities

Even when separation is the right choice, treat the employee with respect and care. Honest communication, consistent documentation and fair evaluations show professionalism and help preserve workplace trust.

Both the Equal Employment Opportunity Commission (EEOC) and the Illinois Department of Human Rights (IDHR) watch disability discrimination claims closely. A single mistake can lead to major legal or reputational costs. Talk with an employment lawyer before you take final action.

Health-related performance issues test your leadership. Keep your policies updated, train your managers and get legal guidance early. These habits help your company stay compliant and make confident, ethical decisions.
