Final answer:
Right-to-work laws secure the rights of employees to join or financially support a labor union. They allow states to decide whether workers can be required to join a union as a condition of employment and provide provisions for disruptive union strikes.
Step-by-step explanation:
The laws that secure the rights of employees to decide for themselves whether or not to join or financially support a labor union are called Right-to-work laws. These laws allow states to decide whether all workers at a firm can be required to join a union as a condition of employment. They also allow the president to declare a 'cooling-off period' during a disruptive union strike, during which the workers have to return to work.
