Irish rocker Bono says he is “deeply sorry” for any abuse employees working for a charity he co-founded may have suffered, months after the first allegations of bullying came out against the ONE charity. The charity, which seeks to end poverty and fight preventable disease, is facing legal action from at least seven former employees who allege abuse and bullying. One employee said she was demoted after refusing to have sex with a Tanzanian minister, while others said they were forced to perform domestic work at a manager’s home. This weekend, months after the first allegations surfaced last November, Bono admitted to The Mail on Sunday that the Johannesburg office of his charity failed to protect employees. “I need to take some responsibility for that,” he said. “The poorest people in the poorest places being bullied by their circumstance is the reason we set up ONE. So to discover last November that there were serious and multiple allegations of bullying in our office in Johannesburg left me and the ONE board reeling and furious,” he said.
