The Taft-Hartley Act is the federal law that amended the National Labor Relations Act in 1947, adding restrictions on unions, protections for individual employees, and procedures for major labor disputes. It remains part of federal labor law, although later legislation and court decisions have changed how some original provisions operate.

What Is the Taft-Hartley Act?
The Taft-Hartley Act is the common name for the Labor Management Relations Act of 1947. Congress enacted it on June 23, 1947, over President Harry S. Truman's veto. It amended the National Labor Relations Act of 1935, commonly called the Wagner Act, rather than replacing that law.
The Wagner Act established a federal framework protecting most private-sector employees' rights to organize, choose representatives, bargain collectively, and participate in other protected concerted activity. It also created the National Labor Relations Board and identified unfair labor practices by employers. Taft-Hartley preserved that basic framework but imposed legal duties and restrictions on labor organizations as well.
The 1947 law also clarified that employees may refrain from union activities, subject to lawful union-security arrangements. It protected certain employer speech, excluded supervisors from the NLRA's definition of employee, authorized state right-to-work laws, and established procedures for labor disputes that could threaten national health or safety.
Taft-Hartley remains in effect, but not every provision operates exactly as it did in 1947. Congress later repealed or revised some requirements, including the original non-communist affidavit requirement for union officers. The Labor Management Reporting and Disclosure Act of 1959, also called the Landrum-Griffin Act, added further union governance, reporting, and member-rights rules. Current questions therefore require examining the NLRA as amended, not relying only on the original 1947 text.
Searches for the Hartley Act, Hartley-Taft Act, or Harley Act generally refer to this same law. The name comes from Senator Robert A. Taft and Representative Fred A. Hartley Jr., its principal congressional sponsors. There is no separate federal labor statute commonly known as the Harley Act in this context.
What Did the 1947 Taft-Hartley Act Change?
Taft-Hartley shifted federal labor policy from regulating primarily employer conduct to regulating conduct by employers and unions. Its supporters described the change as a way to balance legal responsibilities. Labor opponents argued that it reduced workers' collective power and gave employers more ways to resist organizing.
The following comparison shows the central changes without treating the Wagner Act and Taft-Hartley as separate modern systems. They now operate together through the amended NLRA.
| Issue | Wagner Act framework | Taft-Hartley change | Party most directly affected |
|---|---|---|---|
| Employee choice | Protected organizing and collective bargaining | Expressly recognized the right to refrain from union activity | Employees and unions |
| Unfair labor practices | Focused on prohibited employer conduct | Added unfair labor practices by labor organizations | Unions |
| Union security | Allowed broader forms of union-security agreements | Prohibited closed shops and permitted states to restrict other union-security arrangements | Employees, unions, and employers |
| Employer communications | Employer opposition could raise interference concerns | Protected expressions of views that contain no threat of reprisal, force, or promise of benefit | Employers and employees |
| Bargaining disputes | Protected collective bargaining and concerted activity | Added notice requirements and national-emergency procedures | Employers and unions |
| Workplace status | Used a broad employee-rights framework | Excluded supervisors from the statutory definition of employee | Supervisors and employers |
The law also allowed employers to petition the NLRB concerning questions of union representation. Both unions and employers must bargain in good faith after a union becomes the employees' recognized bargaining representative. For a broader view of day-to-day workplace communication and conflict prevention, see these employee relations strategies.
Taft-Hartley did not abolish unions, collective bargaining, or lawful strikes. Instead, it defined additional boundaries around organizing, bargaining, picketing, union security, and economic pressure. The legality of particular conduct depends on its purpose, target, participants, applicable agreement, and statutory exceptions.
Union Practices Restricted by Taft-Hartley
The Hartley Act amendments identified several forms of union conduct as unfair labor practices or otherwise restricted them. One major example is a secondary boycott. A primary labor dispute concerns the employer with which the union has the disagreement. Secondary activity pressures a neutral business to stop dealing with the primary employer. Federal law restricts specified forms of that secondary pressure, although detailed exceptions and industry-specific rules may apply.
Taft-Hartley also restricted jurisdictional strikes, which seek to force an employer to assign particular work to one group of employees instead of another. It prohibited closed-shop arrangements requiring an employer to hire only existing union members. A union shop, under which employees may have obligations after hiring, is legally different. Any such arrangement must comply with federal law and the law of the state where the employees work.
Section 14(b) permits states to adopt right-to-work laws restricting agreements that condition continued employment on union membership or related payments. Right-to-work does not mean that employees lose their right to organize or bargain collectively. It addresses union-security obligations, not the general existence of a union.
The law also addresses coercion of employees, excessive or discriminatory membership fees, certain recognition picketing, featherbedding demands, and refusals to bargain in good faith. Later amendments further developed some of these restrictions. Employers remain subject to their own unfair labor practice rules, including prohibitions against interfering with protected organizing, dominating a labor organization, or discriminating based on protected union activity.
Taft-Hartley does not make every broad or coordinated strike automatically illegal. A general strike may create legal issues if its conduct amounts to a prohibited secondary boycott, violates a lawful no-strike obligation, involves workers outside the NLRA's coverage, or conflicts with another applicable law. The label placed on a strike does not decide its legality. The conduct, objective, parties, governing contract, and statutory rules do.
National-Emergency Strikes and the 80-Day Process
Taft-Hartley's national-emergency provisions apply to an actual or threatened strike or lockout affecting a substantial part of an industry involved in interstate or foreign commerce when continuation of the dispute would imperil national health or safety. The procedure is exceptional. It does not allow a president to end any strike simply because it causes economic disruption or public inconvenience.
The president initiates the process by appointing a board of inquiry to investigate and report on the dispute. The board identifies the facts and the parties' positions, but it does not issue a binding resolution. After receiving the report, the president may direct the attorney general to seek an injunction in federal district court. The court, not the president acting alone, decides whether the statutory requirements support an injunction.
If the court grants relief, the strike or lockout may be suspended for up to 80 days while operations resume and bargaining continues. This period is often called the 80-day cooling-off period. The injunction does not impose a collective bargaining agreement, select a winning proposal, or permanently prohibit a strike. Its purpose is to create time for negotiations while avoiding an immediate threat to national health or safety.
The process includes further reporting and procedures relating to the parties' positions before the injunction ends. If the dispute remains unresolved, federal officials report to Congress. The parties may then remain free to use otherwise lawful economic action once the court order expires, subject to their contract and other labor laws.
This national-emergency process differs from ordinary mediation. The Federal Mediation and Conciliation Service helps employers and unions resolve bargaining disputes through neutral mediation and conciliation. The FMCS does not adjudicate unfair labor practice charges or certify bargaining representatives. Those functions belong to the NLRB. Mediation can assist negotiations, but parties should also understand the potential disadvantages of mediation when the dispute requires immediate legal relief or a binding ruling.
What Taft-Hartley Means for Employers, Workers, and Unions
For employers, Taft-Hartley permits noncoercive communication about unionization while preserving strict limits on threats, retaliation, surveillance, promises of benefits, and interference with protected activity. An employer facing an organizing campaign should coordinate communications, manager training, document retention, bargaining obligations, and responses to information requests. A supervisor's status also matters because supervisors do not receive the same NLRA organizing protections as covered employees.
Workers generally retain the right to support a union, oppose one, discuss workplace conditions, act together regarding employment concerns, and participate in representation proceedings. Those rights depend on coverage and context. Federal labor law does not cover every worker, and special rules may apply to public employees, agricultural laborers, independent contractors, supervisors, and employees governed by other statutes.
Unions must avoid prohibited coercion and specified secondary or jurisdictional conduct. They also owe bargaining duties when representing employees. Before calling a strike, establishing a picket line, pursuing recognition, or enforcing a union-security clause, a union should review the collective bargaining agreement, statutory notice requirements, right-to-work rules, and the objective of the planned action.
Collective bargaining agreements can contain grievance procedures, arbitration clauses, no-strike provisions, management-rights clauses, and detailed rules for discipline or work assignments. Federal courts may enforce qualifying labor contracts, while the NLRB addresses conduct within its statutory jurisdiction. This division means that one dispute can involve contract interpretation and an unfair labor practice question. Employers with government contracts should also avoid confusing Taft-Hartley with the separate Service Contract Act requirements, which concern wage and benefit standards for certain federal service contracts.
If you face an organizing campaign, disputed union-security clause, boycott, strike, lockout, or NLRB matter, you can post your legal need on UpCounsel's marketplace. A labor attorney can evaluate the conduct and governing agreements, explain the available NLRB, court, bargaining, or mediation procedures, and prepare or respond to filings and negotiations. Responses typically arrive within a day, helping you identify immediate compliance risks before taking action.
Taft-Hartley does not replace wage-and-hour requirements. Questions about breaks, overtime, and working time arise under other federal or state rules, which are addressed in this overview of federal and state break laws.
Historical Context, the Red Scare, and Later Amendments
Congress passed Taft-Hartley after major labor unrest following World War II. Wartime restrictions had limited strikes in critical industries, but postwar disputes affected transportation, manufacturing, mining, and other parts of the economy. The 1946 elections gave Republicans control of Congress, creating political support for limiting union power and revising New Deal labor policy.
The early Cold War also shaped the statute. Fear of communist influence within labor organizations formed part of the political case for requiring union officers to submit affidavits stating that they were not Communist Party members or supporters of organizations advocating the government's overthrow by force or unlawful means. A union whose officers did not comply could not use certain NLRB processes.
President Truman opposed the legislation and vetoed it, but Congress overrode the veto. Critics viewed the law as an attack on organized labor and workers' ability to act collectively. Supporters argued that unions, like employers, should face defined unfair labor practice rules and that the public needed protection from labor disputes threatening essential national interests.
The non-communist affidavit provision tied Taft-Hartley directly to the Red Scare, but it is not a current filing requirement. The Labor Management Reporting and Disclosure Act of 1959 repealed that requirement and made other changes. That 1959 law also established rights for union members, imposed reporting and disclosure duties, regulated union elections, and strengthened restrictions involving certain secondary activity.
Other original Taft-Hartley procedures were revised or superseded after 1947. This distinction matters when reading an original Taft-Hartley Act PDF or historical summary. The original text shows what Congress enacted, but the current United States Code, later statutes, court decisions, and NLRB interpretations determine present obligations.
The law's continuing significance comes from the structure it established. Modern federal labor policy still protects organizing and collective bargaining while regulating employer and union conduct. Disagreement over that balance explains why Taft-Hartley remains a recurring subject in debates about right-to-work laws, strike power, union organizing, and proposed labor-law reform.
Frequently Asked Questions
Is the Taft-Hartley Act still in effect?
Yes, the Taft-Hartley Act remains in effect as part of the amended National Labor Relations Act. You should not assume that every rule in the original 1947 enactment remains unchanged, however. Congress repealed some provisions and added others, while courts and the NLRB have interpreted the statute over time. Current conduct must be evaluated under the law and agency rules now in force.
What was the Taft-Hartley Act, and what impact did it have on labor unions after 1947?
The Taft-Hartley Act was a 1947 amendment that placed new federal restrictions and duties on labor organizations. After enactment, unions faced limits on certain boycotts, picketing, union-security arrangements, and strike objectives. The law also gave employers additional procedural and speech protections. Critics say these rules weakened organizing leverage, while supporters view them as checks against coercive or economically disruptive conduct.
Did President Carter invoke Taft-Hartley during the 1977 longshoremen strike?
No, President Jimmy Carter did not invoke Taft-Hartley's national-emergency injunction procedure during the 1977 International Longshoremen's Association strike. His administration considered the dispute and monitored its economic effects, but it did not use the statute to seek an 80-day injunction. This example shows that a serious transportation strike does not automatically trigger presidential intervention under the law.
How many times has the Taft-Hartley national-emergency provision been invoked?
There is no reliable single total unless the term "invoked" is defined. Historical counts may separately track presidential boards of inquiry, requests for injunctions, court-issued injunctions, and distinct disputes involving multiple proceedings. Because those measures produce different totals, use the stated counting method and date range when citing a figure rather than presenting every presidential action as a completed 80-day injunction.
How did the Taft-Hartley Act of 1947 reflect the goals of the Red Scare?
The law reflected Red Scare goals by conditioning unions' access to certain NLRB procedures on non-communist affidavits from union officers. The requirement sought to remove communist influence from organized labor during the early Cold War. It also placed political beliefs and affiliations inside federal labor regulation, which generated substantial opposition. Congress later repealed the affidavit requirement, so it is now historical rather than an active union obligation.
Are general strikes illegal under the Taft-Hartley Act?
No, Taft-Hartley does not use a simple rule declaring every general strike illegal. A broad strike may nevertheless lose protection or violate federal law when it pursues a prohibited secondary or jurisdictional objective. Other restrictions may come from a collective bargaining agreement, public-sector law, industry-specific legislation, or rules governing workers outside the NLRA. Legality therefore turns on the action's participants, purpose, target, and governing law.
