I have been asked many times by clients and candidates what is the number one reason that will cause a person to make a job change. A few years ago I night have said geography, travel or possibly a long commute. What it all boils down to is quality of life. Today's economic climate have caused a great deal of stress on everyone and when I ask a person what would drive them to a new opportunity I am constantly hearing: I need to get a better work/life balance.
Lesson learned. Money is not the driving factor.
