Key Facts About Employment in Illinois

Employment Contracts in Illinois
Illinois generally follows at-will employment, meaning either party may end the relationship at any time for any lawful reason, absent a contract or a protected characteristic.
- Most employers use offer letters rather than formal contracts. An offer letter commonly states the title, start date, pay rate, pay frequency, exempt or nonexempt status, work location, and at-will language.
- There is no statewide "wage theft prevention" notice equivalent to New York's, but the Illinois Wage Payment and Collection Act requires employers to notify employees at the time of hiring of their rate of pay and the time and place of payment, in writing whenever possible, and to notify them of changes before they take effect.
- Roles may be full-time, part-time, temporary, seasonal, fixed-term, or filled by independent contractors, and classification affects eligibility for benefits and leave. Independent contractor classification is closely scrutinized in Illinois, particularly in construction, and misclassification can create liability for unpaid wages, unemployment insurance contributions, and workers' compensation.
- Illinois restricts restrictive covenants under the Illinois Freedom to Work Act. Noncompete agreements are void for employees earning at or below a defined salary threshold that increases over time, and nonsolicitation restrictions have their own earnings floor, so employers should confirm the current thresholds before requiring these terms. Confidentiality agreements remain widely used.
