This is the site I found with this map.
A Right to Work (click here) law secures the right of employees to decide for themselves whether or not to join or financially support a union. However, employees who work in the railway or airline industries are not protected by a Right to Work law, and employees who work on a federal enclave may not be. Moreover, a Right to Work law does not prohibit limitations on when a dues deduction authorization card can be revoked. Workers should carefully read the fine print before signing such a card....
Now, put your thinking caps on.
Is there nothing about that map above that hasn't appeared somewhere else?
Let me help.
Hint: Think ACA.
Still not yet?
There is a direct relationship between poverty and states without the ACA or unions.
