Unfair Labor Practice
Definition
An unfair labor practice (ULP) is an action by an employer or a union that violates the National Labor Relations Act, such as interfering with employees' right to organize or act together, or refusing to bargain in good faith. Charges go to the National Labor Relations Board, and they apply in non-union workplaces too.
Also called: ULP, NLRB unfair labor practice, ULP charge
The employer unfair labor practices
Section 8(a) of the NLRA lists five kinds of employer ULP:
- Interfering with, restraining or coercing employees in exercising their Section 7 rights to organize, join a union, bargain collectively or act together for mutual aid or protection.
- Dominating or interfering with the formation or administration of a labor organization, or supporting one financially.
- Discriminating in hiring, firing or any term of employment to encourage or discourage union membership.
- Retaliating against an employee for filing charges or testifying under the Act.
- Refusing to bargain in good faith with the employees' chosen representative.
Section 8(b) lists parallel practices by unions, such as coercing employees or refusing to bargain in good faith with the employer.
ULPs in workplaces without a union
Many HR teams assume the NLRA only matters where there is a union. In fact, Section 7 protects "concerted activity" by non-supervisory employees whether or not a union exists. Some common examples that lead to charges:
- A handbook rule telling employees not to discuss their pay with each other
- Firing an agent who posted on social media, with coworkers, about understaffing and unpaid overtime
- Questioning employees about union interest or promising raises if they vote against a union
- Broad confidentiality instructions in investigations that stop employees from talking about working conditions
- Disciplining a group of warehouse workers who walked off a shift together over a safety concern
The NLRB's standard for judging handbook rules has shifted several times over the past decade, so review rules on confidentiality, social media and recording against current Board guidance.
How a ULP charge works
Anyone (an employee, a union or the employer) can file a charge with an NLRB regional office, generally within six months of the conduct. The region investigates, often asking the employer for a position statement and documents. If it finds merit, it tries to settle; otherwise the Regional Director issues a complaint and the case goes before an administrative law judge, with appeal to the Board and then federal court.
Remedies are designed to restore the situation, not punish: reinstatement, back pay, rescinding unlawful rules and posting a notice to employees. They can still be costly, and a posted notice in the break room is not something leadership wants.
How HR avoids ULPs
Train supervisors on what not to do during organizing activity: no threats, interrogation, promises or surveillance. Review the handbook every year for rules that could chill protected discussion. Before disciplining anyone for complaints, posts or walkouts, ask whether the conduct involved coworkers and working conditions; if so, get labor counsel involved. Where a union exists, bargain over mandatory subjects such as wages, hours and working conditions before changing them, and follow the grievance steps in the contract. For more on that process, see collective bargaining and retaliation.
The NLRA covers most private-sector employers but excludes supervisors, managers, agricultural and domestic workers and independent contractors. Public-sector employees fall under state law.
Frequently asked questions
What is an example of an unfair labor practice?
Firing an employee for discussing pay with coworkers, threatening to close a site if employees unionize, or refusing to bargain with a certified union are all classic examples of employer unfair labor practices.
Who enforces unfair labor practice rules?
The National Labor Relations Board. Charges are filed with an NLRB regional office, which investigates and can issue a complaint heard by an administrative law judge.
How long do you have to file an NLRB unfair labor practice charge?
Generally six months from the date of the alleged unfair labor practice, under Section 10(b) of the NLRA.
Can a union commit an unfair labor practice?
Yes. Section 8(b) of the NLRA lists union ULPs, including coercing employees in exercising their rights, causing an employer to discriminate against an employee, and refusing to bargain in good faith.
