Consult or freelance
Many consulting companies need people to come in on a project basis, says Dick Dawson, vice president of CareerCurve, who coaches many workers over age 55. "Explore the company -- write to the person who heads up the unit you would want to work in." Other organizations, especially those that are downsizing, look for freelancers to fill gaps in their staff. Try online bidding sites, like PeoplePerHour.com, to find this kind of work.
