People who are wrongfully incarcerated then exonerated, sometimes after spending decades behind bars, face yet more challenges finding jobs and rebuilding their lives after their release. Advocates say exonerees lack work history, viable skills, training and references when seeking work. Advocates and exonerees say they also face bias and stigma, even though they have been found innocent. National nonprofits and local groups are working to provide employment opportunities and other assistance for exonerees. The National Registry of Exonerations reports that more than 3,800 people have been exonerated in the U.S. since 1989.
