DUBLIN/NEW YORK (Reuters) - Over 1,000 Google employees and contractors in Asia, Europe and the United States staged brief midday walk-outs on Thursday, with more expected to follow at California headquarters, amid complaints of sexism, racism and unchecked executive power in their workplace. Hundreds of women and men filed out of Google’s office in New York City and silently walked around the block for about 10 minutes around 11:00 a.m. ET.
