The Fairness Center takes no position on whether you should or should not be a union member. Many unions have rules that govern whether and how members who have resigned can rejoin, so you should be familiar with the rules of your specific union if you are concerned about this issue.
NOTE: If you have questions about this topic, or think you have a legal issue, consider contacting a lawyer. Fairness Center lawyers represent clients for free and can be reached here or at 844.293.1001. We strongly encourage you to pursue with haste any legal claim you believe you may have, as the mere passage of time may prevent you from exercising possible legal claims.
