I'd disqualify convicts (meaning felony, and in this case, particularly financial or access-related crimes) from physical security custodian roles (such as locksmithing), probably child care, probably financial stewardship. If it's a person with a drug crime history, probably nothing in the pharmacy chain of custody. Nothing in law enforcement. There are exceptions, and famously if someone's going to be providing quality information based on a "nefarious past" like Frank Abagnale, sure, but for a low-level clerk position, eliminating risk by barring 5% of the population from 5% of the jobs (not even particularly good ones) is a reasonable tradeoff. I'd trust an ex-con with finances of the cash register variety, but not unsupervised and unaccounted-for access to large amounts of cash. (It's not something you'd want to have to trust an $8-12/hr employee with in general, but in some cases it's unavoidable.) If someone had higher skills (say, an auto mechanic who was also convicted of a serious felony), the risk/reward of having that person working as an auto mechanic is probably a lot better than a low skill person taking a key cutter job vs. another form of retail job.
