Hundreds of Google employees and contractors in Asia staged brief midday walkouts on Thursday.
At Google’s global headquarters in Mountain View, California, hundreds of employees streamed into a courtyard holding protest signs.
In New York City, women and men filed out of Google’s office and silently walked around the block for 10 minutes.
Thousands more are expected to follow at offices worldwide, amid complaints of sexism, racism and unchecked executive power in their workplace.
Employees are asking for changes in Google’s human resources practices intended to make bringing harassment claims a fairer process.
Google Chief Executive Sundar Pichai said in a statement that “employees have raised constructive ideas”.
