What is Modern Slavery?
While definitions vary, in this report the term modern slavery refers to situations where one person has taken away another person’s freedom — their freedom to control their body, their freedom to choose to refuse certain work or to stop working — so that they can be exploited. Freedom is taken away by threats, violence, coercion, abuse of power and deception. The net result is that a person cannot refuse or leave the situation.
Our award winning team of experts have over 50 years experience in the anti-slavery and counter trafficking sector.
The Walk Free Foundation holds biannual expert working groups with academics and anti- modern slavery experts from around the world.

Phil Marshall has been working on programmes to combat human trafficking and forced labour for the past 18 years. Phil is currently focusing on emerging approaches to trafficking including work to combat exploitative labour practices through targeting supply chains, government procurement practices and proceeds of crime. Phil has a particular interest in 1) ensuring that the design of programmes to respond to trafficking and forced labour are better aligned with accumulated knowledge within and outside of the sector, and 2) the potential to “crowd out” exploitative business practice through initiatives such as the development of cleaner migration pathways and the promotion of ethical buying behaviour.
