This whole criminal record piece of shit is a crime on its own. I believe that records of people who served their time or just have been arrested/carded and then let free must be sealed and not accessible to general employers.
Some obvious exceptions can apply but generally people should not be penalized for what they've been penalized already.
Are they now? I see no reason why they should as long as it does not fall under special exception list. Like pedos working in kindergarten. But attempt to hire those would raise that special exception flag anyways.
They are externalizing that liability on to the rest of society then. It's obviously in everybody's interests that convicted criminals can get jobs outside of crime.
