George getting his old job back, however, could disrupt their routine, causing them to fall back into their old toxic patterns, putting the family at risk.

As revealed on The Big Bang Theory, George's affair is imminent in the prequel. This means that eventually, George and Mary's marriage will crumble, and it won't just be because he gets his old job back. The pair's fate has long been pre-determined.

Like Sheldon, Mary tended to rag on George on The Big Bang Theory. She rarely had anything good to say about her husband even though he had been dead for years already when the nerd-centric sitcom began. This suggests that Mary harbors a deep and big grudge against her husband, although it's unclear whether it mainly stems from his extra-marital affair.
