Brenda O'Neill is one of several hundred men and women working as nannies and au pairs in the suburbs of Pittsburgh, Pennsylvania. In conversations with several of the nannies and au pairs she knows, she learns that they are paid vastly different amounts $($some receive less than minimum wage$)$ and are often not provided basic benefits, such as the ability to take a sick day or short vacations. She is planning to start a domestic workers' union for the Pittsburgh area, but learns that her friends' employers are threatening to fire them if they continue to meet with Brenda about these issues.

True or false: Brenda and her fellow domestic workers can turn to the National Labor Relations Act for legal protections for their right to unionize.
