What is a Right-To-Work state?
If you are employed in one of 22 Non-Right-to-Work states (also called Forced Dues states) and the union negotiates a “union (income) security clause” you could be required to pay the union as a condition of employment.
If you refuse to pay a union under a union income security clause, the union can order you to be fired from your job.
However, if you work in a Right-to-Work state, it is illegal for a union to require you to pay dues as a condition of employment.
