A sample union resignation letter is provided below.

[LETTER TO UNION:

SEND BY CERTIFIED MAIL,

RETURN RECEIPT REQUESTED]

[your address]

[date]

[name and address of union]

[To the appropriate union officer]:
I hereby resign as a member of [name of union]. My resignation is effective
immediately. I will continue
to meet my lawful obligation of paying a representation fee to the union
under its "union shop" or "agency shop" agreement with
[name of employer].

Furthermore, I object to the collection and expenditure by the union of
a fee for any purpose other than my pro rata share of the union’s costs
of collective bargaining, contract administration, and grievance adjustment,
as is my right under Ellis
v. BRAC, 466 U.S. 435 (1984). Pursuant to Chicago
Teachers Union v. Hudson, 475 U.S. 292 (1986), I request that you
provide me with my procedural rights, including: reduction of my fees to
an amount that includes only lawfully chargeable costs; notice of the calculation
of that amount, verified by an independent certified public accountant;
and notice of the procedure that you have adopted to hold my fees in an
interest-bearing escrow account and give me an opportunity to challenge
your calculation and have it reviewed by an impartial decisionmaker.

[If you pay dues by payroll deduction, include this paragraph:
Accordingly, I also hereby notify you that I wish to authorize only the
deduction of representation fees from my wages. If I am required to sign
a new deduction authorization form to make that change, please provide me
with the necessary form.]

Please reply promptly to my request. Any further collection or expenditure
of dues or fees from me made without the procedural safeguards required
by law will violate my rights under the Railway
Labor Act and/or U.S. Constitution.

Finally, please consider this objection to be permanent and continuing
in nature.

Sincerely yours,
[name]

If you include the paragraph on the change in your payroll deduction authorization,
you should also send a copy of this letter to the payroll department of your employer.
