Chief Executive Sundar Pichai apparently announced the stricter policies in a memo to workers.
"Over the past few weeks, Google's leaders and I have heard your feedback and have been moved by the stories you've share," Pichai writes in the memo. "We recognize that we have not always gotten everything right in the past and we are sincerely sorry for that. It's clear we need to make some changes."
The CEO goes on to promise more transparency, provide better support and to "double down" efforts to become a more respectful workplace.
Among the policy changes Pichai outlines are options to make arbitration available on a case-by-case basis for claims of harassment or assault; changes to how it investigates and hears claims of abuse; and update and expand training for employees.
"Our Chief Diversity Officer will continue to provide monthly progress updates to me and my leadership team," adds Pichai.
About 20,000 employees staged a massive walkout on Nov. 1 over how its top leaders handled accusations of sexual misconduct at the company.
The demonstration followed a New York Times expose on how the tech giant rewarded Andy Rubin, founder of the Android operating system, with $90 million despite an accusation of sexual coercion.
