Union Organizing Rights in Michigan: What Workers Can Do

The National Labor Relations Act (NLRA), codified at 29 U.S.C. § 151 et seq., is the primary federal statute protecting union organizing rights. Section 7 of the NLRA (29 U.S.C. § 157) explicitly grants all covered employees the right to organize, form labor organizations, bargain collectively, and engage in concerted activities for mutual aid or protection.

Section 8(a) of the NLRA (29 U.S.C. § 158(a)) prohibits employers from interfering with these rights. Prohibited conduct includes: interrogating employees about union sympathies or activities; threatening employees with adverse consequences (discharge, discipline, loss of benefits) for union support; creating the impression of surveillance of union activities; and discriminating against employees based on union membership or activity. The NLRA applies to private-sector employers engaged in interstate commerce, covering approximately 60 million workers nationally.

The National Labor Relations Board (NLRB), a federal agency established under the NLRA, enforces these protections. When a union or employee files an unfair labor practice charge alleging employer violation, the NLRB investigates and, if merit is found, seeks to remedy the violation through reinstatement with back pay, posting of notices, and in some cases attorney fees. Section 9 of the NLRA (29 U.S.C. § 159) establishes the framework for union certification elections, whereby the NLRB conducts secret ballot elections to determine whether employees wish union representation. Federal law also protects employees' right to refuse union participation in right-to-work states.

Michigan is a right-to-work state under Public Act 396 of 2012 (MCL 423.1 et seq.), which fundamentally shapes union organizing in the state. Under Michigan's right-to-work law, employers cannot require employees to join a union, pay union dues, or pay a service fee as a condition of employment. This means that even if a union is certified and represents a bargaining unit, individual employees cannot be terminated for refusing union membership or dues payment.

Michigan's law does not create additional organizing rights beyond the federal NLRA; rather, it restricts unions' ability to maintain union security agreements (closed shops or agency shops) that were previously permitted in many states. The statute applies to all private and public employers in Michigan, overriding previous contractual union security provisions and limiting future agreements to non-disparagement or fair-share arrangements only in limited circumstances.

While Michigan does not strengthen organizing protections federally provided, it creates a unique organizing environment: unions must convince workers to voluntarily participate financially and structurally, even after certification. Organizers cannot rely on dues checkoff systems or member discipline enforcement to sustain membership. This makes Michigan organizing campaigns more challenging for unions seeking to build power and fund operations.

Michigan state labor law does not independently protect union organizing outside the NLRA's scope. Instead, Michigan courts and the Michigan Department of Labor defer to NLRB determinations on unfair labor practices and representation matters. Remedies available under state law mirror federal remedies: NLRB reinstatement orders, back pay calculations determined by the NLRB, and posting of legal notices. However, right-to-work status means unions face structural disadvantages in sustaining membership density, potentially weakening bargaining power even after successful certification.

Several important exceptions and limitations apply to union organizing in Michigan. The NLRA excludes certain categories: supervisors, independent contractors, government employees (covered under separate Public Employment Relations Act), agricultural workers, and domestic employees in private homes are not protected. Additionally, confidential employees whose primary duties involve handling labor relations or interpreting company labor policy are excluded from bargaining units.

Employers have limited legal defenses to organizing activity allegations. An employer can restrict union solicitation during work time if the restriction applies to all non-work solicitation equally and does not target union activity specifically. Employers may prohibit distribution of literature in production areas if applied consistently to all organizations. However, employees retain the right to organize during breaks and off-duty time, and the employer cannot create special restrictions for union activity alone.

Under Michigan's right-to-work law, employers can require that all employees (union and non-union) be hired through identical processes and paid equally; this is not considered discrimination against union supporters. Furthermore, unions cannot enforce union security agreements requiring membership or dues payment, eliminating the union's ability to exclude non-paying members from benefits or institute disciplinary measures based on non-compliance.

Another critical exception involves the at-will employment relationship in Michigan. While the NLRA protects organizing activity, at-will employment means an employer can discharge an employee for any legal reason unrelated to union activity. The burden falls on the charging party to prove discrimination was motivated by anti-union animus; employers can often defend discharge decisions by citing legitimate business reasons (attendance, performance, policy violation) unrelated to protected activity. Additionally, the statute of limitations for unfair labor practice charges is 180 days, meaning allegations of violations occurring more than six months prior cannot be remedied through NLRB processes.

Step 1 – Document the Violation. Keep detailed records of any employer conduct you believe violates your organizing rights. Document dates, times, locations, and exact language of any interrogation ("Do you support the union?"), threats ("We will close if unionized"), surveillance ("We noticed union flyers in the parking lot"), or discriminatory treatment. Save emails, text messages, and written notices from management. Record the names of witnesses and any coworkers who experienced similar treatment. Photography of posted notices or evidence of differential treatment strengthens your case. Maintain copies in a secure location outside the workplace.

Step 2 – Consider Internal Processes. Before filing externally, determine whether your union has an internal grievance process or whether the employer has established complaint procedures. Some unions have representatives available to discuss potential violations and guide next steps. However, internal processes are not required before filing with the NLRB, and pursuing them does not extend the 180-day filing deadline. If you file internally, do so in writing and keep copies. Internal complaints create additional evidence and may prompt employer corrective action, but the NLRB ultimately has jurisdiction over unfair labor practice allegations.

Step 3 – File an Unfair Labor Practice Charge with the NLRB. You must file within 180 days of the violation. Visit the NLRB website (www.nlrb.gov) and locate your regional office—Michigan is covered by NLRB Region 7 (Detroit field office). Charges can be filed online through the NLRB E-Government system, by mail, or in person. Required information includes: your name and contact details, the employer's name and address, specific dates and descriptions of the alleged violations, and the nature of the alleged unfair labor practice (retaliation, interrogation, interference, discrimination). Clearly identify whether the violation occurred during organizing activity or union representation. Filing is free and confidential at the outset.
