Facing a wave of employee theft, retailers across the country have helped amass vast databases of workers accused of stealing and are using that information to keep employees from working again in the industry.

The repositories of information, like First Advantage Corporation’s Esteem database, often contain scant details about suspected thefts and routinely do not involve criminal charges. Still, the information can be enough to scuttle a job candidate’s chances.

Some of the employees, who submit written statements after being questioned by store security officers, have no idea that they admitted committing a theft or that the information will remain in databases, according to interviews with consumer lawyers, regulators and employees.

The databases, which have tens of thousands of subscribers and are used by major retailers like Target, CVS and Family Dollar, are aimed at combating employee theft, which accounts for a large swath of missing merchandise. The latest figures available, from 2011, put the loss at about 44 percent of missing merchandise, valued at about $15 billion, according to a trade group, the National Retail Federation.
