Google said Thursday it fired 48 employees in the past two years — including 13 senior executives — as a result of sexual harassment allegations, citing “an increasingly hard line” on inappropriate conduct. The US tech giant issued the statement from chief executive Sundar Pichai in response to a New York Times report that one senior Google employee, Android creator Andy Rubin, received an exit package worth $90 million as he faced allegations of misconduct, and that Google had covered up other claims of sexual harassment.
