8.1 NLRA Foundations and Protected Concerted Activity

Why the NLRA dominates the labor domain

The National Labor Relations Act (NLRA), also called the Wagner Act of 1935 and amended by the Taft-Hartley Act of 1947 and Landrum-Griffin Act of 1959, is the spine of U.S. private-sector labor law. On the 2026 PHR exam (115 items: 90 scored plus 25 unscored pretest questions, 2 hours), Employee and Labor Relations carries 20% weight — the largest of the five functional areas — so several labor items are nearly guaranteed.

The NLRA is enforced by the National Labor Relations Board (NLRB), an independent federal agency. It covers most private employers but excludes supervisors, agricultural and domestic workers, independent contractors, public-sector employees, and railway/airline workers (covered by the Railway Labor Act instead). PHR distractors love to claim the Act applies only after a union exists — it does not.

A brief history clarifies the structure for the exam. The Wagner Act (1935) created Section 7 rights and the employer ULPs in Section 8(a), tilting the law toward organizing during the Depression. The Taft-Hartley Act (1947) rebalanced it by adding the right to refrain from union activity, the union ULPs in Section 8(b), the 80-day national-emergency strike injunction, and Section 14(b) permitting state right-to-work laws. The Landrum-Griffin Act (1959), formally the Labor-Management Reporting and Disclosure Act, added internal-union democracy protections (a union members' bill of rights) and financial-disclosure duties.

Knowing which amendment did what is a recurring PHR item.

Section 7 and protected concerted activity

Section 7 is the heart of the statute. It gives employees the right to:

• Self-organize, form, join, or assist a labor organization
• Bargain collectively through representatives of their choosing
• Engage in concerted activities for mutual aid or protection
• Refrain from any of the above (the Taft-Hartley addition)

Protected concerted activity (PCA) exists when two or more employees act together — or one employee acts on behalf of others or to induce group action — about a term or condition of employment. Critically, this protection applies in nonunion workplaces. Employees comparing wages, jointly complaining about scheduling, or circulating a petition about safety are usually engaged in PCA. A purely individual gripe advancing only the speaker's interest is generally not protected.

Activity loses protection if it is egregious — violence, sabotage, defamation made with reckless disregard for truth, or disparagement of the product unconnected to a labor dispute. Workplace rules that broadly ban discussing pay are themselves unlawful.

Section 8(a) employer unfair labor practices and the TIPS rule

Section 8(a) lists employer unfair labor practices (ULPs):

The TIPS acronym captures the most common 8(a)(1) traps managers fall into: do not Threaten (loss of jobs/benefits), Interrogate (ask who supports a union), Promise (raises or perks to discourage organizing), or Surveil (watch or photograph protected activity, or create the impression of surveillance). The lawful counterpart is FOE — employers may share Facts, Opinions, and Examples.

Section 8(b) union unfair labor practices and other rights

The statute is even-handed. Section 8(b) lists union ULPs: restraining or coercing employees in their Section 7 choices, causing an employer to discriminate, refusing to bargain in good faith, engaging in unlawful secondary boycotts, charging excessive initiation fees, and featherbedding (forcing payment for work not performed). PHR items occasionally test that the union, not only the employer, can commit a violation.

Two more frameworks shape rights. Right-to-work laws, permitted under Taft-Hartley Section 14(b), exist in roughly 26 states and bar union-security clauses that require membership or dues as a condition of employment; in non-right-to-work states a contract may require dues or fair-share fees. Under Janus v. AFSCME (2018), public-sector employees cannot be compelled to pay agency fees — but Janus is a public-sector ruling and does not change private-sector NLRA rules, a frequent distractor.

Worked PHR scenario

Three warehouse associates email their manager together objecting to a new mandatory-overtime rule, and the manager wants to discipline them for insubordination. The PHR-correct move: first assess whether this is PCA (it is — two-plus employees acting together about working conditions), confirm the rule is being applied consistently to everyone, and avoid any TIPS conduct or retaliation. Document the legitimate business reason for the rule and apply progressive discipline neutrally if a genuine performance issue exists, separate from the protected complaint.

Common traps: assuming a nonunion setting means the NLRA is irrelevant; treating a joint complaint as misconduct without analysis; or maintaining an overbroad social-media or confidentiality policy that an employee could reasonably read to chill protected discussion of wages and conditions.

Remedies and the NLRB process

When the NLRB finds a violation, remedies are make-whole rather than punitive: reinstatement of unlawfully discharged employees, back pay with interest (and, under recent Board doctrine, consequential financial harms), rescission of unlawful rules, and the posting and reading of a notice promising not to repeat the conduct. There are no compensatory or punitive damages like a discrimination lawsuit. Charges must be filed within six months of the violation, the Regional Office investigates, and meritorious cases proceed before an Administrative Law Judge, then potentially the five-member Board and a federal court of appeals.

For HR, the takeaway is preventive: train supervisors on Section 7 and TIPS, keep neutral and consistently applied policies, and document legitimate business reasons before acting, because the cheapest ULP is the one that never happens.
