> The way you motivate someone who doesn’t need the money is the same way you should motivate people who do need the money: by giving them meaningful roles with real responsibility where they can see how their efforts contribute to a larger whole
Completely misses the point: the manager needs Jean, not the way around.
Not to mention, Jean could just plain refuse to take on the "meaningful" role, if she likes what she does now and how things are going currently.
Whatcha gonna do if the "meaningful role" isn't so meaningful to her?
Some people just don't understand: Jean is probably in a better position than both the manager asking the question and the person giving the "advice".
The manager just can't have leverage over her.
