My managers at the coffee shop seemed to understand that they weren’t allowed to fire me solely for talking about pay, but they may not have known that it is also illegal to discourage employees from discussing their pay with each other. As NYU law professor Cynthia Estlund explained to NPR, the law “means that you and your co-workers get to talk together about things that matter to you at work.” Even “a nudge from the boss saying ‘we don’t do that around here’ … is also unlawful under the National Labor Relations Act,” Estlund added.
.. Given their illegality, why are gag rules so common? One answer is that the NLRA is toothless and employers know it. When employees file complaints, the National Labor Relations Board’s“remedies” are slaps on the wrist: reinstatement for wrongful termination, back-pay, and/or “informational remedies” such as “the posting of a notice by the employer promising to not violate the law.”
