You can thank Joseph Macktal Jr., a 1980s nuclear power whistleblower, for this one. Macktal raised safety concerns at his plant in Texas, was fired, and threatened into signing an NDA. He later legally challenged and publicized that NDA, which said that if he ever told anyone about the secret settlement, Brown & Root could sue him, retrieve all their settlement money, and force Macktal to pay all the company’s attorney fees and costs. Macktal contended that the secret settlement violated federal law by prohibiting him from communicating with the government about his nuclear safety concerns.
