WASHINGTON — Google said Thursday that it had reached a settlement with the National Labor Relations Board over complaints from multiple employees who say the company has stymied dissent, including one who has said he was fired for being an outspoken conservative.

Google plans to explain to employees the rights they have as workers under federal law, like the ability to discuss workplace conditions, said Jenn Kaiser, a Google spokeswoman. And it will tell the employees that Google will not retaliate against them for exercising those rights.

“Under that settlement, we have agreed to post a notice to our employees reminding them of their rights under the National Labor Relations Act,” Ms. Kaiser said in a statement. “As a part of that notice, we will also remind employees of the changes we made to our workplace policies back in 2016 and 2017 that clarified those policies do not prevent employees from discussing workplace issues.”

The settlement requires the approval of an official at the N.L.R.B. According to a document obtained by The New York Times, a regional director said this week that she was approving the settlement.
