It would be a very uncomfortable workplace for him and his wife to work in even if he was cleared. Possibly a
PR problem for the company also.
It would all depend on the circumstances. At the end of the day if you are found not guilty by a court you are not guilty regardless of whatever your colleagues or employer may believe. The more difficult scenario would be if the Police drop the charges due lack of evidence. That would probably be the more difficult position to be in as there was never a test of the accusations against you and people will be forever wondering if you are a some crazy serial killer or just unlucky. Unfortunately these days too Police seem pretty good with their forensics so they usually don't just charge random people for no reason so if the charges were to be dropped then it would only fester speculation.
