Postal workers cannot legally go on strike. Federal law bars every employee of the United States Postal Service, along with all other federal workers, from participating in a strike against the government. The prohibition carries criminal penalties, automatic job loss, and a permanent ban from future federal employment. In place of strikes, postal unions resolve disputes with USPS management through collective bargaining and, when that fails, binding arbitration.
The Federal Law Behind the Ban
The rule comes from a statute covering all federal employees, not one written just for the Postal Service. Under 5 USC 7311, no one may accept or hold a position with the U.S. government if they participate in a strike against the government or even assert the right to do so.1Office of the Law Revision Counsel. 5 USC 7311 – Loyalty and Striking The same section disqualifies anyone who belongs to an organization that claims the right to strike against the government.
Every federal worker signs an affidavit as a condition of employment affirming they will not strike. Refuse to sign, and you don’t get the job. That makes the commitment personal. Every postal employee has individually promised, in writing, not to walk out.
Private-sector workers have broad strike protections under the National Labor Relations Act, which is why walkouts happen at automakers, hospitals, and grocery chains. Federal employment sits under a separate legal framework, and the right to withhold labor does not exist within it.
Penalties for a Postal Worker Who Strikes
A postal employee who joins a strike faces three separate consequences.
The job is forfeit. Because the law says you cannot hold a federal position if you strike, walking off the job ends the employment immediately.1Office of the Law Revision Counsel. 5 USC 7311 – Loyalty and Striking The same provision bars rehiring by any federal agency afterward, not just USPS.
Striking against the government is also a Class E felony. Conviction carries a fine, imprisonment of up to one year and a day, or both.2Office of the Law Revision Counsel. 18 USC 1918 – Disloyalty and Asserting the Right to Strike Against the Government3Office of the Law Revision Counsel. 18 USC 3559 – Sentencing Classification of Offenses
One point of clarification on retirement: a strike conviction does not automatically forfeit federal pension benefits. The forfeiture statutes target espionage, treason, and similar offenses, not strike-related convictions.4Office of the Law Revision Counsel. 5 USC Part III, Subpart G, Chapter 83, Subchapter II – Forfeiture of Annuities and Retired Pay Lying on an employment application about ties to a striking organization is a separate matter and can lead to pension forfeiture.
What Happens to a Union That Calls a Strike
The consequences reach the union too. Federal law makes it an unfair labor practice for any labor organization to call, participate in, or condone a strike, work stoppage, or slowdown against the government.5Office of the Law Revision Counsel. 5 USC 7116 – Unfair Labor Practices A union that willfully violates this rule can lose its exclusive recognition status, which is granted and revoked by the Federal Labor Relations Authority.6Office of the Law Revision Counsel. 5 USC 7120 – Standards of Conduct for Labor Organizations
Decertification would strip a union of its legal authority to represent employees and negotiate contracts. For organizations like the American Postal Workers Union and the National Association of Letter Carriers, whose entire purpose is bargaining over pay, benefits, and working conditions, that outcome would be catastrophic. The threat keeps union leadership firmly opposed to strike talk, even when frustration with management runs high.
How Postal Labor Disputes Actually Get Resolved
With strikes off the table, federal law lays out a three-stage process for resolving postal labor disputes. Each stage escalates if the previous one fails.
Collective Bargaining
Direct negotiation between USPS and the postal unions is the starting point. These talks cover pay rates, health benefits, scheduling, workplace safety, and every other term of employment. USPS currently holds collective bargaining agreements with multiple unions covering hundreds of thousands of employees.7United States Postal Service. Chapter 1 Compliance with Statutory Policies – Employee Compensation and Career Advancement Either side can trigger bargaining on a new contract by giving written notice at least 90 days before the current agreement expires.8Office of the Law Revision Counsel. 39 USC 1207 – Labor Disputes
Mediation
If no agreement is reached within 45 days, the Federal Mediation and Conciliation Service steps in. Its director appoints a mediator who is nationally recognized and a member of the National Academy of Arbitrators. Both sides must negotiate in good faith at times and places the mediator directs.8Office of the Law Revision Counsel. 39 USC 1207 – Labor Disputes
Binding Arbitration
If mediation still hasn’t produced a deal 60 days after the old contract expires, the dispute goes to binding arbitration. A three-member panel is formed: USPS picks one member, the union picks one, and those two select the third. If they can’t agree, the Mediation and Conciliation Service director provides a list of qualified arbitrators to choose from. The panel hears both sides and issues a decision within 45 days. That decision is final and legally binding on the union and the Postal Service.8Office of the Law Revision Counsel. 39 USC 1207 – Labor Disputes
This is where the absence of strike power is felt most sharply. In the private sector, a credible threat to walk out gives unions leverage. In postal negotiations, leverage depends on the strength of arguments before an arbitrator. Arbitration awards have ranged from substantial raises to terms closer to what management offered, so the process is not automatically favorable to either side.
What Postal Workers Are Allowed to Do
The law that bans strikes carves out one form of collective action: peaceful informational picketing that does not interfere with agency operations is not an unfair labor practice.5Office of the Law Revision Counsel. 5 USC 7116 – Unfair Labor Practices
Postal employees can picket on public sidewalks outside postal facilities to draw attention to workplace issues. They cannot picket inside buildings, block entrances or exits, or otherwise prevent the public from using the facility. USPS has confirmed that employees who picket lawfully while on approved leave or on their own time cannot be disciplined for it, and they may wear their postal uniforms while doing so.
The line between protected picketing and an illegal work stoppage is sharp. Picketing that interferes with mail processing or delivery crosses into unfair labor practice territory. If workers collectively refuse to report for their shifts, that is a strike, whether or not anyone uses the word.
Individual Appeals for Adverse Job Actions
Separate from union bargaining, individual postal employees have their own path for challenging unfavorable job actions. Preference-eligible veterans with at least one year of continuous service, along with certain supervisors and managers, can appeal adverse employment actions to the Merit Systems Protection Board.9U.S. Merit Systems Protection Board. Jurisdiction
Appealable actions include firings, suspensions longer than 14 days, reductions in pay or grade, and short-term furloughs. Employees covered by a union grievance procedure generally must use that process first, though an exception lets them go directly to the Board for serious adverse actions. That gives individual workers a check on management decisions outside the collective bargaining system.
The Two Precedents Every Postal Union Remembers
Two federal-employee strikes shape how postal unions think about the law today, and they point in opposite directions.
In March 1970, more than 200,000 postal workers walked off the job in a wildcat strike that began in New York City and spread across more than a dozen states. It was the largest federal-employee strike in American history. President Nixon deployed roughly 23,000 military personnel to New York to sort mail, and they could not do the job. After eight days, the government negotiated, and workers returned with a preliminary agreement that included a 6 percent wage increase. Not a single striker was fired. That strike produced the Postal Reorganization Act, signed August 12, 1970, which created the modern USPS and gave postal unions the right to bargain collectively over wages, hours, and working conditions.10National Postal Museum. Transforming the Post Office11Office of the Law Revision Counsel. 39 USC Chapter 12 – Employee-Management Agreements
The 1981 air traffic controllers’ strike went the other way. Over 12,000 members of the Professional Air Traffic Controllers Organization walked out. President Reagan gave them 48 hours to return, then fired every controller who stayed out and banned them from federal rehire. PATCO leaders were arrested. The union was decertified. The rehiring ban lasted until 1993.
PATCO is the precedent that dominates postal labor relations now. It confirmed that the government has both the legal authority and the political will to enforce the no-strike law to its fullest. Every postal union leader since 1981 has understood that the next federal strike could follow the PATCO pattern rather than the 1970 one, and that knowledge shapes every negotiation.
