Should you use AI to tackle workplace harassment?

Post #MeToo, employers have become increasingly focused on tackling harassment. In fact, it was recently reported that some companies are implementing monitoring software that uses AI to detect online harassment at work. The technology is said to use algorithms that recognise harassing or bullying language within internal worker emails and online chats, which are then flagged to HR for investigation. But is this really the correct tool to combat workplace harassment? And are there better ways for employers to protect workers?
