Roughly how long one should stay on before leaving? Because sometimes it might be due to 'timing' issue, like perhaps need a while more before those gaps in expectations will eventually be closed.

Understand it definitely will not look nice on the person to leave so soon after starting out in the job (the person is not a serial quitter, has worked for many years in previous jobs), hence when would be a "responsible" or "reasonable" period to quit after realizing that it is impossible to patch up those expectation gaps?

Because think it is neither good to hang on for too long if one realize it is not a good fit (it is not good for the employee nor for the employer, as no one will want to retain a disconnected staff anyway).
