More than 70 women have told the BBC they have been sexually exploited by their supervisors on farms owned by Unilever, Lipton, and other popular brands.
The BBC also captured a moment on camera where a supervisor of a Kenyan tea farm is seen with an undercover reporter and he asks her to touch him and undress. On another plantation, the same undercover reporter attended an induction day for new recruits where a manager gave a speech saying the company had a Zero Tolerance sexual harassment policy.
The manager invited her to meet him in a hotel bar that evening and suggested later that they go to his compound. Some of the women interviewed work is scarce and they felt that they did not have any options. The BBC investigation is still underway. Lipton, which bought one of the plantations from Unilever, has also launched an investigation.
