Google parent Alphabet Inc. faced a wave of critical proposals from activists and employees during its annual shareholder meeting Wednesday, including one to split up the internet search and ad-selling giant before regulators break it into pieces.

None of the handful of proposals was passed according to a preliminary tally, but they illustrate rising discontent among some investors and the rank-and-file over the company on several fronts, such as sexual harassment risk management, inequitable employment practices, and backlash to Google’s search work in China. One proposal sought to put an employee representative on the board.

In shareholder materials, Alphabet said its current policies address the proposed measures. It declined further comment.

The odds of any plan winning support was all but nil. Alphabet’s top two executives, Larry Page and Sergey Brin, hold 51.3% of shareholder votes. A newly constituted 10-member board, minus former Google CEO Eric Schmidt and Google Cloud head Diane Greene -- both of whom did not seek re-election -- was approved.

“Officials in the US and EU continue to be concerned about Alphabet’s market power in view of restrictions on monopolies,” SumOfUs, a U.S.-based group that aims to curb the growing power of corporations, wrote in a proposal. “We believe that shareholders could receive greater value from a voluntary strategic reduction in the size of the company than from asset sales compelled by regulators.”

The meeting, held at an auditorium at the company’s offices in Sunnyvale, Calif., comes amid mounting pressures on big tech companies to rein in their considerable power and burnish their corporate images.

FB, +0.20% , and Amazon.com Inc. AMZN, +0.66% Presidential candidate Sen. Elizabeth Warren (D., Mass.) has made the break-up of Google, Amazon, and Facebook a key part of her platform.

Employees and outside activists have spent nearly two years trying to make Google more accountable to workers, shareholders, and the cities in which it operates.

Despite the rejection of activist proposals, Google has responded to petitions from employees and critics by vowing to halt work on a censored Chinese search engine and ban use of its artificial intelligence tools for weaponry.

“Of course this comes with a deep and growing responsibility to ensure the technology we create benefits society as a whole,” Alphabet Chairman John Hennessy said in opening the meeting. “We are committed to supporting our users, our employees and our shareholders by always acting responsibly, inclusively and fairly.”
