The companies can hire whoever they want however they want within the law. They certainly could not hire this bloke.

However, if they want to hire someone who only has accusations against him, I don't see the problem. Businesses can and do hire full-fledged known criminals (typically after they've paid their legal penalty); and this is better for us all then having them uselessly sitting around. Many of them will still be perfectly good workers. Having done something illegal doesn't mean getting ejected from society; being accused certainly doesn't.
