That's a good question.
Plus, what if you are a self employed person that's only doing 20 hours a week? Or you cut your rate down so that a 40 hour week pays the same as a 30 hour week?
Course that's a hard question to ask "Would you like to make more money in a week?" Gee, I wonder. Perhaps a "Are you making more or less money than you did a year ago"

Or, in my case, I'm employed full time as a professor, but I have a consulting "business" that accounts for between 10-20% of my annual income. (In past years, it was much more). Am I employed by one, but not the other? Should I be DOUBLE counted?
