Google has sacked 48 people including 13 senior managers over sexual harassment claims since 2016.
In a letter to employees, chief executive Sundar Pichai said the tech giant was taking a "hard line" on inappropriate conduct.
The letter was in response to a New York Times report that Android creator Andy Rubin received a $90m exit package despite facing misconduct allegations.
A spokesman for Mr Rubin denied the allegations, the newspaper said.
Sam Singer said Mr Rubin decided to leave Google in 2014 to launch a venture capital firm and technology incubator called Playground.
He was given what the paper described as a "hero's farewell" when he departed.
Mr Pichai's letter said the New York Times story was "difficult to read" and that Google was "dead serious" about providing a "safe and inclusive workplace".
"We want to assure you that we review every single complaint about sexual harassment or inappropriate conduct, we investigate and we take action," he continued.
