Rand Paul is getting a petition together to introduce a Right-to-Work Bill in congress that would make it illegal at the federal level to compel any employee to join a labor union as a prerequisite for employment.
Unions extort with threats of violence, over $8billion dollars from American workers every year, regardless of whether the employees are democrat, republican, or apolitical. A federal Right-to-Work bill would end that and make union membership entirely voluntary without punishment for abstaining.
You can click the link and sign the petition and of course, you are encouraged to donate to the cause. As political causes go, this would be a good one to throw some money at.
