"management never forgives and never forgets"
Oh yes it does. It'll completely forget all the all-nighters you've done and all the times you stayed after hours for no additional pay in order to make sure that everything would go well the next day for that very important presentation.
That is all water under the bridge, especially when review time comes.
But it will remember that one time you didn't manage to make the CEOs new bloody phone sychronize automatically with his company-based mail because you needed a bridge component the company didn't have.
That he will always remember.
