The main reasons Illinois denies unemployment claims

Illinois denies unemployment claims for three broad categories of reasons: how you left your job, how you behaved at work, and facts about your employment itself. The Illinois Department of Employment Security (IDES) reviews each claim against these rules, and if any one applies to you, your claim will be denied—even if other parts of your situation seem to fit.

The most common disqualifications are voluntary resignation without good cause, being fired for misconduct, and not being able to work or be available for work. But there are others that catch people by surprise: being self-employed, working for certain government agencies, or having already been paid for the same period through another program.

Understanding which rule might explore to you matters because some disqualifications are permanent (you cannot fix them), while others are temporary (they last only a certain number of weeks). A few can be appealed if IDES made a factual error about what happened.

Key Takeaways

  • Quitting your job without good cause—meaning a reason connected to the work itself, not personal circumstances—disqualifies you for the entire period you are out of work.
  • Being fired for misconduct (willful or negligent violation of workplace rules) disqualifies you, but being fired for poor performance or inability to do the job does not.
  • You must be able and available to work; if you are in school full-time, caring for a child with no backup, or physically unable to work, you cannot collect.
  • Self-employed workers, certain government employees, and workers in some religious organizations are not covered by Illinois unemployment insurance at all.
  • If you were paid for the same week through another program (workers' compensation, disability, severance), you may not also collect unemployment for that week.

Leaving your job voluntarily without good cause

If you quit, IDES must determine whether you had good cause. This does not mean you had a good reason—it means you had a reason connected to the work itself that made staying impossible or unreasonable. Personal reasons, even serious ones, do not count.

Good cause includes: unsafe working conditions that violate health or safety law, a substantial and unjustified cut in pay or hours, being asked to do something illegal, or a pattern of harassment or discrimination by management. It does NOT include: needing to care for a family member, moving to a new city, going back to school, conflict with coworkers, or disliking your boss.

If IDES finds you quit without good cause, you are disqualified for the entire period you remain unemployed—not just a few weeks. This is one of the harshest disqualifications in the system. You can appeal if you believe the facts about why you left are wrong, but the standard for what counts as good cause is narrow.

Being fired for misconduct

Being fired does not automatically disqualify you. IDES distinguishes between three types of termination: misconduct, poor performance, and inability to do the job. Only misconduct disqualifies you.

Misconduct means you willfully or negligently violated a reasonable workplace rule or standard of conduct. Examples: showing up drunk, stealing, deliberately ignoring a direct instruction, or repeated tardiness after being warned. Poor performance—you tried but could not meet the standard—is not misconduct. Neither is being let go because you lack the skills for the role or because the employer made a bad hiring decision.

The employer must show that you knew (or should have known) the rule, that the rule was reasonable, and that you broke it willfully or through gross negligence. If your employer fired you but cannot prove misconduct, your claim should be approved. You can appeal if IDES sides with the employer and you believe the facts are wrong.

Not being able or available to work

To collect unemployment in Illinois, you must be able to work and available to work. This is checked when you file and again each week you claim benefits.

You are not able to work if you are physically or mentally unable to perform any job you are may have access to for. This includes being in the hospital, having a serious injury or illness that prevents work, or being pregnant and unable to work. It does not include being tired, having a cold, or having a job offer that starts in two weeks.

You are not available to work if you are in school full-time, caring for a child with no childcare arrangement, unable to work your usual hours, or not actively looking for work. If you tell IDES you will not work certain hours or in certain locations, you may be found unavailable. If you are collecting unemployment and then take a full-time school course, you will be disqualified for those weeks.

Employment types not covered by Illinois unemployment insurance

Some workers are not covered by the Illinois unemployment insurance system at all, so they cannot collect no matter what their situation is. This is a structural disqualification—it is about who you worked for, not how you left or behaved.

Self-employed workers are not covered. If you owned the business or were a partner, you cannot collect. Government employees are covered only if they work for a city, county, or school district; state employees and federal employees are not covered by the standard program (though some federal employees can collect under a separate program). Workers for certain religious organizations are not covered if the organization has exempted itself from the system. Domestic workers (housekeepers, nannies, caregivers in private homes) are covered only if the household paid at least $1,000 in wages in a calendar quarter.

If you fall into one of these categories, you cannot collect Illinois unemployment. Some may be covered by other programs—federal employees by the Federal Employees Compensation Act (FECA), for example—but that is a separate process.

Receiving other payments for the same period

You cannot collect unemployment for a week in which you received payment from another source for the same period. The most common overlap is workers' compensation. If you are collecting workers' comp for a work injury, you cannot also collect unemployment for those weeks, even if you are not working.

The same rule applies to disability benefits (state or federal), severance pay, and vacation or sick pay your employer paid out after you left. If your employer paid you for two weeks of unused vacation when you were laid off, you cannot collect unemployment for those two weeks. If you receive a lump-sum severance, IDES will calculate how many weeks it covers based on your usual weekly wage and disqualify you for that period.

Report any other payments to IDES when you file. If you do not and IDES finds out later, you may be required to repay the benefits you collected.

Refusing work or failing to report

If you refuse a suitable job offer without good cause, you are disqualified. Suitable work means work in your field or a related field at a wage close to what you earned before. You cannot refuse a job straightforward because it pays less or is not your ideal role.

You must also report to IDES each week you claim benefits and answer questions honestly. If you fail to report, your claim is suspended. If you report false information—about your income, your job search, or your availability—you can be disqualified and required to repay benefits.

Other disqualifications and special situations

You are disqualified if you left work to relocate with a spouse and could not find work in the new location within a reasonable time. You are also disqualified if you were laid off due to a labor dispute (strike or lockout) at your workplace, though this disqualification ends once the dispute is settled.

If you are receiving Supplemental Security Income (SSI) or certain other means-tested benefits, collecting unemployment may affect your may be able to access for those programs. This is not an unemployment disqualification, but it is a reason to check with the other program before you claim.

If you were fired for a single incident of poor judgment or a first-time mistake—even a serious one—you may not be disqualified if it does not rise to the level of willful misconduct. IDES looks at the severity, whether you were warned, and whether the rule was clearly communicated.

Frequently Asked Questions

Can I collect unemployment if I quit because of health problems?

Not unless the health problem was caused by the job itself (like a workplace injury or exposure to hazardous conditions). Quitting because you have a medical condition that makes work difficult, even if serious, is not good cause. You may be covered under disability programs instead.

What if I was fired but my employer did not document the misconduct?

IDES will ask your employer to explain why they fired you. If they cannot show that you willfully or negligently violated a rule, your claim should be approved. You can also provide your own account of what happened. Documentation helps, but the burden is on the employer to prove misconduct.

If I am in school part-time and working part-time, can I collect unemployment?

Yes, as long as you are available to work full-time if a job is offered. Part-time school does not make you unavailable. Full-time school does, so if you enroll in a full-time program, you will be disqualified for those weeks.

Does being laid off due to lack of work disqualify me?

No. Lack of work is not misconduct and is not your fault. You should be approved unless another disqualification applies (like receiving severance that covers the period, or not being available to work).

What happens if I appeal and IDES denies my appeal?

You can request a hearing before an administrative law judge. You will have a chance to present evidence and testimony about what happened. If you lose the hearing, you can appeal to the Illinois Unemployment Insurance Board of Review. Many people win on appeal because they can present facts that were not clear in the written claim.
