A dues checkoff revocation window is the short period each year, or at contract expiration, when you can legally cancel the payroll deduction of union dues from your paycheck. Under Section 302(c)(4) of the Labor Management Relations Act, a checkoff authorization cannot be irrevocable for more than one year or beyond the expiration of your collective bargaining agreement, whichever comes first.1Office of the Law Revision Counsel. 29 USC 186 – Restrictions on Financial Transactions Miss the window, and the authorization renews for another year.
The Annual Anniversary Window
The most common opportunity to revoke comes once a year, near the anniversary of the date you signed your checkoff authorization card. The exact length of the window is set by the card itself or by your collective bargaining agreement. Some open ten days before the anniversary. Others run 15 or 20 days. If you signed on June 1, your window might run from roughly May 12 through May 22.
The window is tied to your individual signature date. Not a calendar year, not a shared open-enrollment period. Two coworkers who signed a month apart have different windows. If you don’t remember when you signed, ask the union or your employer’s payroll department for a copy of your authorization card well before you think the window opens. Waiting until you believe the window is open to start asking is how most workers miss it.
When the window closes without a valid revocation, the authorization renews automatically. Courts treat these timing restrictions as enforceable contract terms, so not knowing the deadline is not a recognized defense.1Office of the Law Revision Counsel. 29 USC 186 – Restrictions on Financial Transactions
The Contract Expiration Window
Because the statute caps irrevocability at the termination date of the collective bargaining agreement, a second opportunity opens whenever the contract between your union and employer expires.1Office of the Law Revision Counsel. 29 USC 186 – Restrictions on Financial Transactions This matters most if you missed your anniversary window or signed at an awkward point in the contract cycle.
One catch: the National Labor Relations Board currently holds that employers must keep honoring existing checkoff arrangements after a contract expires, at least until a successor agreement is reached or the parties hit a genuine bargaining impasse.2National Labor Relations Board. NLRB Rules Employers May Not Unilaterally Stop Union Dues Checkoff When Collective Bargaining Agreement Expires The employer will not stop deductions on its own just because the contract has lapsed. You still need to affirmatively revoke. But the statutory cap on irrevocability means the employer cannot refuse your revocation by pointing to the old contract’s renewal clause.
If negotiations drag on for months, the window stays open during that gap. Once a successor agreement is ratified, you are back under whatever checkoff terms the new contract establishes. Tracking your union’s negotiation timeline is the only way to spot this window as it opens.
Resigning the Union Is Not the Same as Revoking Checkoff
This is where most people get caught. Resigning your union membership and revoking your dues checkoff authorization are two separate legal actions. You can quit the union at any time. But if you don’t also revoke the checkoff authorization during a valid window, your employer will keep deducting dues and sending them to the union.
The authorization card is a standalone contract between you and your employer. The union’s records of your membership status do not control it. Workers who resign without revoking checkoff often watch deductions continue for months and assume someone made a mistake. It isn’t a mistake. Payroll follows the card, not the membership roll. To actually stop deductions you need both: a resignation letter to the union and a timely revocation of the checkoff authorization.
Writing and Delivering the Revocation
Your revocation notice needs to be in writing. Include your full legal name, employee identification number, and the union local number. State clearly that you are revoking your dues checkoff authorization. Legal jargon isn’t required. A sentence like “I revoke my authorization for payroll deduction of union dues, effective immediately” is enough, as long as it is unambiguous.
Before you draft, pull a copy of your original authorization card or the relevant section of your collective bargaining agreement. Some cards specify exact language or procedures. If the card says “written notice to the employer,” send it there. If it says “written notice to the employer and the union,” send it to both.
Delivery Method
The card or CBA may specify how notice must be delivered. Some older contracts require certified mail. The NLRB’s General Counsel has taken the position that a certified mail requirement can itself be an unlawful impediment to revocation if it discourages employees from exercising their rights. Either way, the safe approach is a delivery method that creates proof: certified mail with return receipt, or hand-delivery with a signed acknowledgment. Email may suffice if your contract does not restrict the delivery method; keep the sent message and any read receipt.
Send the notice to both your employer’s payroll department and the union’s financial officer, even if the card only names one recipient. Doing both eliminates any argument that the right party wasn’t informed. Keep copies of everything: the notice, the proof of delivery, and the authorization card itself.
After You Send It
Payroll departments generally stop deductions within one or two pay cycles after processing a valid revocation. Check your pay stubs. If deductions continue past the second cycle, follow up in writing with payroll and keep copies of that follow-up. Persistent deductions after a timely revocation are the kind of problem that escalates.
Right-to-Work States
Twenty-six states have right-to-work laws, which mean you cannot be required to join a union or pay dues as a condition of employment. If you never signed a checkoff authorization, there is nothing to revoke.
But if you did voluntarily sign a checkoff card in a right-to-work state, the card’s contractual terms still govern when and how you can revoke. The right-to-work statute protects you from being fired for refusing to pay dues; it does not automatically override the window periods in an authorization you voluntarily signed. The timing rules above still apply. If you are in a right-to-work state, never signed a card, and are still seeing deductions, contact payroll first, and if the deductions continue, consider filing a charge with the NLRB.
Public Sector Employees After Janus
Everything above applies to private sector workers covered by the National Labor Relations Act. Public sector employees operate under a different framework after the Supreme Court’s 2018 decision in Janus v. AFSCME, which held that no payment to a public-sector union may be deducted from an employee’s wages without affirmative consent.3Justia. Janus v AFSCME
If you are a public sector employee who never joined the union, no fees can be deducted without your clear agreement. The old “agency fee” or “fair share” system is gone. If you joined and signed a dues authorization, though, several federal courts have ruled that the membership agreement is a contract and that window periods in it can be enforced against you even after Janus. State laws and executive orders governing public-sector labor relations vary widely, so your revocation rights depend on your state’s rules and the specific terms of your authorization.
If Your Window Isn’t Open Yet: Beck Rights
You may be able to reduce what you pay even before your next revocation window. Under Communications Workers of America v. Beck, employees who object to full union membership can become “financial core” members, paying only the portion of dues that covers collective bargaining and contract administration rather than the union’s full budget.4Justia. Communications Workers of America v Beck That typically excludes political activities, lobbying, and organizing at other workplaces. Unions are required to notify covered employees about this option.5National Labor Relations Board. Employer/Union Rights and Obligations You can object at any time; you don’t need to wait for a revocation window.
When Deductions Continue Anyway
If your employer or union keeps deducting dues after you submitted a valid revocation during the correct window, you can file an unfair labor practice charge with the NLRB. The charge goes to the regional office covering the area where the violation occurred, and you can locate yours through the NLRB’s website.6National Labor Relations Board. Investigate Charges
You complete NLRB Form 501 for a charge against an employer, or Form 508 for a charge against a union, depending on who is failing to honor your revocation. Attach your proof of delivery and a copy of the revocation notice. There is no filing fee, you do not need a lawyer, and an information officer at your regional office can help you complete the form. If the Board finds merit, it can investigate and issue a complaint on your behalf at no cost.
The deadline is strict. Under Section 10(b) of the National Labor Relations Act, no complaint can issue based on a violation that occurred more than six months before the charge was filed.7Office of the Law Revision Counsel. 29 USC 160 – Prevention of Unfair Labor Practices If your employer has been deducting dues for eight months after a valid revocation and you file only now, you may recover only for the most recent six months. File as soon as it is clear the deductions are not going to stop.
