Collective Bargaining Rights in Illinois: Worker Protections

The National Labor Relations Act (NLRA), 29 U.S.C. section 157, establishes the federal foundation for collective bargaining rights in the United States. Section 7 of the NLRA gives employees in the private sector the right to organize, form unions, and bargain collectively with employers without interference, restraint, or coercion. The law applies to employers engaged in interstate commerce with employees in the United States, with limited exceptions for railroads, airlines, and certain other industries.

Section 8 of the NLRA, 29 U.S.C. section 158, defines unfair labor practices that employers cannot commit. These include interfering with employees' rights to organize, dominating or assisting labor organizations, discriminating against employees for union activity, retaliating against employees who file unfair labor practice charges, or refusing to bargain in good faith with a union representative. Employers are also prohibited from surveillance of union activities, interrogating employees about union sympathies, and threatening consequences for unionizing.

The National Labor Relations Board (NLRB), a federal independent agency, enforces the NLRA. Employees can file charges alleging unfair labor practices with the NLRB's regional offices. The NLRB investigates charges and may seek remedies including reinstatement of wrongfully terminated employees, back pay, and cease-and-desist orders. The NLRB also oversees representation elections when employees seek to unionize a workplace. Coverage extends to most private sector employers, but excludes certain government employees, railroads and airlines (covered under the Railway Labor Act), agricultural workers, and domestic employees.

Illinois provides both complementary and additional protections for collective bargaining through two state statutes: the Illinois Public Labor Relations Act (5 ILCS 315/1 et seq.) and the Illinois Labor Relations Act (820 ILCS 260/1 et seq.).

The Illinois Public Labor Relations Act (PLRA) governs collective bargaining rights for public sector employees in Illinois, including state and local government employees. Unlike private sector employees who have robust federal NLRA protections, public sector employees in Illinois have limited bargaining rights. The PLRA permits public employees to organize and bargain collectively, but the scope is narrower than the NLRA. Bargaining may be restricted to wages, hours, and working conditions, and certain managerial functions are typically excluded. Illinois public sector employees cannot strike; strikes by public employees are illegal under state law. The Illinois Labor Relations Board (ILRB) or the Illinois Public Labor Relations Board enforces the PLRA and investigates unfair labor practice complaints.

The Illinois Labor Relations Act (ILRA), 820 ILCS 260/1 et seq., supplements federal NLRA protections for private sector employees. Illinois state law parallels the federal law but may provide additional procedural protections or remedies. Under the ILRA, private sector employees have the right to self-organize, form labor organizations, and bargain collectively. The law prohibits employers from interfering with these rights, discriminating against employees for union membership, or retaliating against employees for protected union activity. Illinois law also protects employees' rights to engage in concerted activity for mutual aid and protection, even outside formal union contexts.

Illinois differs from federal law in several ways. First, Illinois explicitly protects secondary boycotts and certain forms of union activity that the NLRA restricts. Second, Illinois provides stricter penalties for certain unfair labor practices. Third, Illinois requires certain employers to recognize unions based on card-check procedures in some circumstances, which exceeds federal law requirements. Fourth, Illinois has a stronger commitment to sectoral bargaining in some industries, particularly in public construction. Finally, Illinois wage and hour laws intersect with collective bargaining—union contracts may establish higher wage floors than the Illinois Minimum Wage Act (820 ILCS 105/1 et seq.), and those union terms control.

Several important exceptions and limitations apply to collective bargaining rights in Illinois.

First, public sector employees in Illinois face significant restrictions. While the Illinois Public Labor Relations Act permits public employee organizing, public employees cannot strike—strikes by government employees are illegal under Illinois law and federal law. Certain categories of public employees, including police officers and firefighters, have separate bargaining frameworks under different Illinois statutes (firefighters under 50 ILCS 305/0.01 et seq., police under 50 ILCS 315/0.01 et seq.). These employees typically have narrower bargaining scopes and different dispute resolution procedures.

Second, certain private sector employees are excluded from NLRA coverage and therefore lack federal collective bargaining protections. Agricultural workers, domestic employees in private households, employees of the U.S. government, employees covered by the Railway Labor Act (railroads and airlines), and supervisors are excluded. Independent contractors are not employees under the NLRA and have no collective bargaining rights.

Third, employers have legitimate defenses to unfair labor practice charges. An employer may discipline or discharge an employee for poor performance, attendance issues, or legitimate business reasons unrelated to union activity, provided the employer can demonstrate the action was not motivated by anti-union animus. Similarly, an employer may refuse to bargain over subjects that are not mandatory subjects of bargaining—permissive subjects include matters of management prerogative such as business decisions, plant closure, and relocation decisions, though some decisions affecting wages must be bargained.

Fourth, at-will employment principles still apply in union and non-union contexts in Illinois. Even with collective bargaining protections, employment remains at-will unless a collective bargaining agreement explicitly provides for just cause or another contractual limitation. However, at-will employment cannot be used as a pretext to retaliate against union activity.

Fifth, certain union activities are not protected. Secondary boycotts, violence, or illegal conduct during labor disputes are not protected under the NLRA, though some secondary boycotts receive greater protection under Illinois law than federal law. Union members who engage in conduct that threatens workplace safety or violates criminal law may lose NLRA protection for that conduct.

If you believe your collective bargaining rights have been violated in Illinois, follow these steps:

**Step 1: Document the Alleged Violation.** From the moment you suspect a violation, keep detailed records of what occurred. Write down the date, time, location, and names of witnesses present when the employer or supervisor allegedly interfered with your union activity, discriminated against you for union membership, interrogated you about union sympathies, or threatened retaliation. Save all written communications—emails, text messages, letters, or memos—that reference union activity or your involvement. Record any changes in your work schedule, pay, benefits, or job duties that coincide with your union activity. Photograph documents related to union organizing (flyers, authorization cards if applicable, meeting notices). Keep copies of your performance evaluations, disciplinary records, and communications showing differential treatment compared to non-union employees. This documentation is critical evidence.

**Step 2: Determine If Your Employer Is Covered and Consider Internal Remedies.** First, confirm whether you work in the private or public sector. If you work for a private sector employer engaged in interstate commerce with at least one employee, you are likely covered by the federal NLRA. If you work for a state or local government agency, your rights are governed by the Illinois Public Labor Relations Act with different procedures and more limited rights. If your workplace is already unionized, consult your union steward or representative before filing a charge. Many collective bargaining agreements include grievance procedures that must be exhausted first. Even if there is no formal grievance process, union leadership can provide guidance on filing an unfair labor practice charge and may provide representation throughout the process.

**Step 3: File an Unfair Labor Practice Charge.** For private sector employees, file a charge with the National Labor Relations Board (NLRB) Regional Office covering your area. Illinois has several NLRB regional offices: the Chicago Regional Office at 209 S. LaSalle Street, Suite 900, Chicago, IL 60604, phone (312) 353-7570. You must file within 180 days of the alleged violation (or 300 days if a state agency has some jurisdiction). The charge form is available online at www.nlrb.gov/resources/forms/uf. Use the UF-1 form (Charge Against Employer). Include your name, address, and phone number; your employer's name, address, and phone number; a clear description of the alleged unfair labor practice with dates; the names of witnesses; and whether union representation is involved. You may file electronically, by mail, or in person at the regional office. File as soon as possible; delays can result in loss of jurisdiction if the 180-day deadline passes.

For public sector employees, file a charge with the Illinois Public Labor Relations Board (PLRB), 160 N. LaSalle Street, Suite 300, Chicago, IL 60601, phone (217) 782-8542. Public sector charges typically must be filed within 30 days of the alleged violation. Use the PLRB charge form available at www2.illinois.gov/idol/pages/laborrelations.aspx. Follow the same documentation approach but be aware that public sector rights are narrower and remedies may be limited.

**Step 4: Investigation and Agency Process.** After filing, the NLRB regional office will review your charge and make a jurisdictional determination. If the office finds jurisdictional issues, your charge may be dismissed. If jurisdiction is established, the NLRB assigns an investigator to your case. The investigator will interview you, witnesses, and the employer's representatives. The investigation typically takes 30-90 days. The investigator will examine evidence and determine whether there is reasonable cause to believe an unfair labor practice occurred. If reasonable cause is found, the NLRB's Regional Director may issue a Complaint. At that point, the case may be heard by an Administrative Law Judge (ALJ) or settled. Settlement discussions may occur at any stage. If the case proceeds to hearing, you will have an opportunity to testify, cross-examine witnesses, and present evidence. The ALJ issues a decision, which either party can appeal to the National Labor Relations Board in Washington, D.C. The entire process from filing to final decision typically takes 12-24 months, though some cases settle faster.

**Step 5: Consult an Attorney and Consider Legal Representation.** Contact a labor law attorney if you face discharge, demotion, or serious discipline allegedly tied to union activity; if you believe the employer has engaged in systematic unfair labor practices affecting multiple employees; if the employer disputes your account and credibility will be central; or if you anticipate the case will proceed to an NLRB hearing. A labor attorney can assess the strength of your case, advise on settlement negotiations, and represent you before the NLRB. Many labor unions provide free or low-cost legal representation to members. If you cannot afford private counsel, contact the National Lawyers Guild (www.nlg.org) or local legal aid societies. Public sector employees facing retaliation should also consult attorneys familiar with the Illinois PLRA and public employee rights.
