Identify where migrants are working, how they got there and what conditions they face: what recruitment agents were used? How much debt are they carrying? Were government officials bribed to facilitate their migration? Do they have access to their passports?
Set clear policies that prevent workers from paying fees to get a job and providing full access to passports.
Build understanding and capability among employers on how to meet those policies.
Ensure that employers only recruit through labor brokers who can demonstrate the understanding and capability to treat workers fairly and lawfully.
