Google has announced a series of actions it is taking in response to the controversy around how women at the company have been treated.

In an email to staff, CEO Sundar Pichai said the company's leaders have listened to employee feedback over the past number of weeks and have been moved by the stories they have heard.

Last week thousands of Google staff around the globe, including hundreds in Dublin, walked off the job for an hour in protest at the situation.

It followed a series of revelations about sexual harassment and misconduct at the company, including a $90m payout to Android inventor Andy Rubin after he had left Google, despite what the firm considered a credible claim of sexual misconduct against him - a claim he denies.

Mr Pichai acknowledged that management at the search giant has not always gotten everything right in the past and he apologised for that.

As a result, he said, the company will provide more transparency about how it handles concerns in the future, including by giving better support and care to people who raise them.

He also published details of an action plan to improve the situation.

Among the measures announced are the introduction of optional arbitration for individual sexual harassment and sexual assault claims.

Mr Pichai claimed that the company had never required confidentiality in the arbitration process and added that it may be the best option, but the choice should be up to the employee, he said.

He also pledged to provide more detail around sexual harassment investigations and outcomes at the company as part of Google's Investigations Report.

The company will also revise the manner in which it will probe employee concerns, including streamlining reporting channels, allowing staff to be accompanied by support persons and offering extra care and resources like counselling and career support during and after the process.

Mandatory sexual harassment training will also be updated and expanded with those not completing training receiving a docking of their performance rating.
