"Google has never required confidentiality in the arbitration process and arbitration still may be the best path for a number of reasons (e.g. personal privacy) but, we recognise that choice should be up to you", Mr Pichai wrote.
Payne Capital Management's Michelle McKinnon and EventShares Chief Investment Officer Ben Phillips on Google employees staging a walkout to protest sexual misconduct allegations at the company and the outlook for the tech sector.
"While Google has championed the language of diversity and inclusion, substantive actions to address systemic racism, increase equity, and stop sexual harassment have been few and far between", the employee statement reads.
At the technology giant's London office near King's Cross station, a crowd of around 100 workers congregated outside. "It's clear we need to make some changes".
Pichai also said Google will provide more details around sexual harassment investigations and outcomes, as well as improving processes used to handle such concerns, including the ability for its employees to be accompanied by a support person.
Responding to demands from the around 20,000 workers who protested last week, the company has said it will end the practice of "forced arbitration" in cases of sexual harassment. Those who fall behind in their training, including top executives, will be dinged in their annual performance reviews, leaving a blemish that could lower their pay and make it more hard to get promoted.
Pichai has promised to collect feedback from workers after they walked out in the wake of a New York Times story that detailed allegations of sexual misconduct against a handful of Google employees including Android software creator Andy Rubin and Richard DeVaul, a director at Google's X lab.
The reforms are the latest fallout from a broader backlash against men's exploitation of their female subordinates. The newspaper said Rubin received a $90-million severance package in 2014 after Google concluded the accusations were credible.
Rubin has denied the allegations.
Critics believe that gender imbalance has created a "brogammer" culture akin to a college fraternity house that treats women as sex objects.
Google isn't addressing another one of the protesters' grievance because it believes it doesn't have merit.
