Had another thought the other day. It may not be a bad idea to set aside what you would be paying in dues into a savings account. If you ever get to a point where you want to rejoin the union, you'll be able to pay all back dues.
It's like when a landlord fails to maintain their property, in a lot of states tenants can withhold rent until repairs are made. You can avoid eviction by proving you are ready and able to pay rent once the property is fixed.
We should petition congress to amend the NLRA to allow for something like this as an extra measure of protection for members who find themselves in a situation like yours.
