Resign SEIU with a letter. It’s easy to do  and you give yourself a raise.
A sample letter how to resign from the  SEIU for private sector employees is attached below.
Non-profit organizations, e.g., San Andreas Regional Center   http://www.sanandreasregional.org/  are an example of a non-profit which requires all employees to join the SEIU.
For California employees, nother helpful organization is the California Professional Employees Association  http://cppea.org/why-choose-cppea/quit-seiu/

[LETTER TO UNION:
SEND BY CERTIFIED MAIL,
RETURN RECEIPT REQUESTED]
[insert your Name]
[insert your Mailing address]
[Date]
[insert Name of appropriate union officer]
[insert Name of union]
[insert Address of union]
Dear [insert Name of appropriate union officer (See your union constitution. For the Teamsters, for example, the letter must be addressed to the Secretary-Treasurer)]:
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 Communications Workers v. Beck, 487 U.S. 735 (1988). Pursuant to Teachers Local 1 v. Hudson, 475 U.S. 292 (1986), and Abrams v. Communications Workers, 59 F.3d 1373 (D.C. Cir. 1995), 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 National Labor Relations 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.]
*Religious Objectors should not use this letter to resign their union membership.*
