A hand on someone's back, complimenting their fragrance - is this a colleague being friendly, or are they crossing a line? What constitutes sexual harassment? BBC Three conducted a social experiment, bringing together 20 people between the ages of 18-30 to see if they understood the rules of behaviour in the workplace. Helen featured in the documentary, sharing her story about how she was a victim of sexual harassment. Helen joins Katie and Dr.Radha to share some advice on ways to deal with sexual harassment and barrister Abigail Bright highlights exactly what sexual harassment is in the eyes of the law, and shares tips on what behaviours are completely unacceptable and should be avoided at all costs.
