Personal finance columnist Michelle Singletar

Personal finance columnist Michelle Singletary is holding a live chat at 11 a.m. Feb. 27 with an author who says that in a world of zero job security, you need to create a stream of income in addition to your regular 9-to-5 job. Singletary’s column appears on Wednesdays and Fridays in The Advocate’s Business pages.

The author is Kimberly Palmer, senior money editor and consumer blogger at U.S. News & World Report. The book is “The Economy of You: Discover Your Inner Entrepreneur and Recession-Proof Your Life.” ”Relying solely on a single employer is a sure-fire way to end up struggling, as so many Americans do,” writes Palmer, whose book suggests ways to create side-jobs for additional income.
