This HBS independent research paper, sponsored by TAMS, builds a clear factbase on how human trafficking operates through the corporate travel ecosystem—and what travel leaders can do about it. It explains the legal and business realities (including liability risk even without intent), the scale of the problem, and why hotels, aviation, and ground transportation are common touchpoints. Most importantly, it offers a practical, action-ready scorecard showing how corporate travel managers can drive awareness, accountability, and measurable change through vendor standards, contract language, traveler communications, and training,starting this week and scaling over the next 12 months.
