Move over Yelp. A new website allows migrant workers to post reviews about recruiters and employers online, using a simple feature phone. It’s called Contratados–”being contracted”–and it allows migrant workers to rate employers and recruiters. With January and February being key times to recruit migrant workers, the developers of the site hope it can be used as a tool to protect workers’ rights.

Contratados was developed by the Center for Migrant Rights through collaborations with design firm StudioRev, worker-owned cooperative Research Action Design and the migrant community organization Migrant Defense Committee.
