The Alphabet Workers Union alleges that Walker violated a federal labor law with the “overly board directive” in a bid to “suppress worker speech” related to the antitrust battles, according to a copy of the Aug. 15 filing obtained by The Post.

“Our employer continues to demonstrate a blatant disregard for federal labor law and our right to discuss working conditions with coworkers—up to and including the proposed remedies of federal antitrust actions that could affect many of our jobs at Google,” said Parul Koul, a Google software engineer and president of Alphabet Workers Union.
