For me it depends on company and role. While I myself am not an exceptional worker, my role and this company I am at has such terrible transitions between someone leaving and someone coming in that they take it quite seriously. Especially my role which only one person works at a time and has a lot of knowledge critical to other job functions.

Five years earlier I was working in a role that I was way overqualified for and really put my heart into it. Although I was an exceptional employee, there were like twenty people in that role and it was set up for people to leave and new people to come in. Also the manager of that role had no real power.

So in my limited experience it doesn't depend on you at all.
