Federal regulators have ordered Google to assure employees they are allowed to speak out on political and workplace issues, people familiar with the matter say, as part of a settlement of formal complaints that the search giant punishes those who do just that.

The National Labor Relations Board’s move offers Google an escape hatch from a thorny issue that has roiled the business in recent years. Though Google executives have long bragged about having a workplace culture designed to encourage open debate, current and former employees across the political spectrum have complained that they were retaliated against for raising concerns about equality and freedom of speech.

The NLRB’s settlement comes in response to a pair of complaints about Google’s reaction to workplace dissent. The settlement orders Google to inform current employees that they are free to speak to the media—without having to ask Google higher-ups for permission—on topics such as workplace diversity and compensation, regardless of whether Google views such topics as inappropriate for the workplace.
