Actually the most apt comparison here is if Bob sends over a contract for $1000, but then goes "oh no I'm sorry, I really meant $800"

There are not takebacks here.

Actually, I know there legally could be, as these situations aren't always black and white, however the company, being such a position of power compared to the employee, loses all goodwill in this situation. If I were in this situation, I would already be sending out feelers.
