Google is accused of imposing an illegal “gag order” prohibiting employees from discussing antitrust matters.

The union representing Google employees is demanding the tech giant lift what it calls an illegal “gag order” that bars them from discussing landmark antitrust cases that could destroy the company’s business.

August 5 US District Judge Amit Mehta ruled that Google is a “monopoly” with illegal control over the online search market.

That same day, Google’s global affairs president, Kent Walker, instructed employees not to comment on the case, either inside or outside the workplace.

The Alphabet Workers union claims Walker violated federal labor law by issuing an “excessive board directive” in an attempt to “suppress worker speech” related to antitrust battles, according to a copy of the Aug. 15 document obtained by The Post.

“Our employer continues to show blatant disregard for federal labor laws and our right to discuss working conditions with co-workers—even to the point of proposed federal antitrust action that could impact many of our jobs at Google,” said Parul Koul, Software Engineer at Google. and president of the Alphabet workers union.

Mehta is expected to decide on a means to combat Google’s search monopoly by next summer.

The Justice Department recently said it may seek to break up Google. by forced sale of part of your businessfor example the Chrome web browser.

Google rejected the union’s complaint.

“We respect the right of Google employees to speak out about the terms and conditions of their employment,” Google spokesman Peter Schottenfels said in a statement. “As is standard practice, we simply ask employees not to talk about ongoing litigation on Google’s behalf without prior permission.”

The Verge newspaper was the first to report this. according to the complaint.

The labor complaint is the latest sign of discord between Google and its employees. In April, the tech giant fired dozens of employees who participated in anti-Israel office sit-ins.

There is also a separate Justice Department antitrust case targeting Google’s alleged monopoly on digital advertising technology. Closing arguments in the case begin next month.

Google CEO Sundar Pichai has acknowledged that the company will likely be tied up in litigation for years as it fights litigation.

In a lengthy statement, the Alphabet Workers Union said it was “critical that workers are involved and that our views and interests are taken into account in the decision-making process regarding antitrust remedies.”

“This has not happened yet,” the union added.

Google vowed to appeal the judge’s decision and rejected the Justice Department’s proposed remedies, calling them “drastic” scope that goes “far beyond the specific legal issues in this case.”
