Sounds like they're missing out on good candidates desperate for a job by having a blanket ban on criminal records instead of only barring those whose specific offense provides a particular reason to think they're unsuitable for the job.

(In more civilized countries, records are sealed and employers submit a potential employees name to the police, who respond with a simple yes/no on whether they have an offense that disqualifies them from that specific job-- i.e. a sex offender wouldn't be allowed to work with kids or vulnerable adults, but would be able to get most other jobs, and a white collar fraudster would be able to work with kids, but not be allowed to work at a bank)
