Being fired during medical leave – or shortly after returning – does not automatically mean your employer violated the law. Illinois generally follows at-will employment, which permits employers to terminate employees for any lawful reason or no stated reason. But an employer cannot fire someone because the employee exercised protected leave rights, requested a disability accommodation, or used legally protected paid leave.
The central issue is not simply whether the termination happened after medical leave. It is whether the leave, medical condition, or accommodation request influenced the decision, and whether the employer’s stated explanation is supported by contemporaneous evidence.
Was Your Leave Protected by the FMLA?
The federal Family and Medical Leave Act (FMLA) provides eligible employees with up to 12 workweeks of unpaid, job-protected leave during a 12-month period for qualifying medical and family reasons.
An employee generally qualifies when:
- The employer is covered by the FMLA;
- The employee has worked for the employer for at least 12 months;
- The employee worked at least 1,250 hours during the preceding 12 months; and
- At least 50 employees work within 75 miles of the employee’s worksite.
An employee returning from FMLA leave ordinarily must be restored to the same position or a virtually identical position. Employers also may not interfere with FMLA rights or treat protected leave as a negative factor when making disciplinary or termination decisions.
A possible FMLA violation may exist if an employer:
- Discouraged you from requesting medical leave;
- Counted protected absences against you under an attendance policy;
- Pressured you to return before approved leave ended;
- Refused to restore you to the same or an equivalent position;
- Suddenly criticized your performance after you requested leave; or
- Terminated you because your absence was inconvenient.
FMLA leave does not provide absolute immunity from termination. An employer may still terminate an employee for an independently legitimate reason, such as documented misconduct, an authentic reduction in force, or a decision demonstrably made before the leave request. The employer should be able to show that it would have made the same decision even if the employee had never taken leave.
What if Your FMLA Leave Expired?
The expiration of FMLA leave does not necessarily end an employer’s legal obligations. A medical condition may qualify as a disability under the Americans with Disabilities Act (ADA). The ADA generally applies to employers with at least 15 employees and may require reasonable accommodations for a qualified employee with a disability. Illinois employees may also have protections under the Illinois Human Rights Act.
A reasonable accommodation can include:
- A limited extension of unpaid medical leave;
- A temporary modified schedule or intermittent leave;
- Changes to nonessential job duties or workplace procedures;
- Remote work when appropriate; or
- Reassignment to a vacant position for which the employee is qualified.
When an employee requests additional leave or provides medical restrictions, the employer generally should communicate with the employee to determine whether a reasonable accommodation would permit a return to work. This is commonly called the interactive process.
An employer may sometimes be required to provide additional unpaid leave even after the employee has exhausted FMLA or employer-provided leave. An employer also generally cannot insist that an employee be fully healed and free of all restrictions if the employee could perform the essential duties of the position with a reasonable accommodation.
An employer does not have to provide an accommodation that would create an undue hardship. Indefinite leave – where the employee cannot say whether or when a return will be possible – may not be required. But an employer should not automatically terminate an employee merely because the employee reached the end of a fixed leave policy.
Short-Term Disability Is Not the Same as Protected Leave
Employees frequently assume that approval for short-term disability benefits means their jobs are protected. That is not necessarily true. Short-term disability insurance generally replaces part of an employee’s income while the employee cannot work. It does not independently guarantee reinstatement.
Job protection may instead arise under the FMLA, the ADA, the Illinois Human Rights Act, an employment agreement, a union contract, or an employer’s written policies. An employer may approve disability payments while separately claiming that the employee exhausted available job-protected leave. Even then, the employer may still need to consider a reasonable accommodation before ending employment.
Illinois and Local Paid-Leave Protections May Also Apply
The Illinois Paid Leave for All Workers Act allows many Illinois employees to earn up to 40 hours of paid leave each year and use it for any reason. Employers generally may not retaliate against employees for exercising rights under the Act. Certain employees and employers are excluded, and different rules may apply when an employer already maintains a qualifying leave policy.
Chicago and Cook County also have local paid-leave requirements. Which law applies may depend on where the employee performs work, the employer’s location, and whether a statutory exception applies.
Warning Signs That the Termination May Have Been Illegal
No single fact proves wrongful termination. However, the following circumstances may justify closer review:
- Suspicious timing. You were fired immediately after requesting leave, while on leave, or shortly after returning.
- Changing explanations. The employer initially said your position was eliminated but later blamed performance, attendance, restructuring, or another reason.
- A sudden negative record. You had positive evaluations and no significant discipline before taking leave, but the employer began documenting supposed performance problems immediately afterward.
- Comments about your absence. A supervisor complained that your leave was burdensome, questioned whether you were really sick, or suggested committed employees would have returned sooner.
- Protected absences counted against you. The employer relied on protected absences when applying an attendance policy, calculating productivity, or imposing discipline.
- No accommodation discussion. You requested additional leave, a modified schedule, or temporary restrictions, but the employer rejected the request without discussing alternatives.
- A questionable job elimination. The employer said the position disappeared, but someone else was hired or assigned to perform substantially the same duties.
- Different treatment. Employees who did not take medical leave committed similar performance or attendance violations but were not terminated.
- No record of when the decision was made. The employer claims the termination decision predated the leave or accommodation request but cannot produce contemporaneous emails, notes, approvals, or draft documents supporting that claim.
When Can an Employer Lawfully Terminate Someone After Leave?
A termination may be lawful when reliable evidence shows that it was unrelated to the employee’s medical condition or protected activity. Examples may include:
- Serious misconduct supported by a consistent investigation;
- Documented performance problems that began before the leave request;
- A legitimate reduction in force affecting comparable employees;
- Elimination of the position based on a plan developed before the leave;
- Failure to provide reasonably requested medical documentation;
- Inability to perform essential job duties even with a reasonable accommodation; or
- A requested accommodation that would cause an undue hardship.
The existence of a stated business reason does not end the analysis. The explanation should be consistent, supported by records created at the time, and applied equally to comparable employees.
What Evidence Should You Preserve?
If you were terminated after medical leave, preserve:
- FMLA applications, approvals, and notices;
- Medical certifications and return-to-work restrictions;
- Accommodation requests and responses;
- Emails, text messages, and workplace chat messages;
- Performance evaluations, disciplinary records, and attendance records;
- Employee handbooks and leave policies;
- Short-term disability documents;
- The termination letter and any severance agreement;
- Job postings for your former position;
- Names of witnesses; and
- A written timeline of significant events.
Keep documents you already lawfully possess, but do not access company systems without authorization or take confidential materials unrelated to your claim. Continue looking for comparable work and retain records of applications, interviews, earnings, and unemployment benefits, which may become relevant to lost-wage damages.
Be Careful Before Signing a Severance Agreement
A severance agreement may require you to release FMLA, disability-discrimination, retaliation, and other employment claims. It may also impose confidentiality, nondisparagement, cooperation, or restrictive-covenant obligations. Do not assume the amount offered reflects the potential value of your claims. Consider having the agreement reviewed before signing, particularly when the termination closely followed protected leave or an accommodation request.
Do Not Wait to Investigate Your Rights
Employment claims have different filing deadlines. In Illinois, an EEOC charge alleging disability discrimination or retaliation generally must be filed within 300 days of the challenged action. The Illinois Department of Human Rights states that most state discrimination charges must be filed within two years. FMLA lawsuits generally have a two-year limitations period, extended to three years for willful violations.
Other claims may have shorter deadlines, and severance negotiations usually do not stop the clock. Employees should seek advice promptly rather than assuming they have years to decide.

The Bottom Line
Being fired after medical leave is not automatically illegal, but an employer cannot use restructuring, attendance rules, or vague performance concerns to conceal retaliation or disability discrimination. The important questions are whether the leave was protected, whether the employer knew about the condition, whether an accommodation was requested, when the termination decision was actually made, and whether the employer’s explanation is consistent with its records and treatment of other employees.
