As a business reporter, I've heard the term "gig economy" a lot.
I've reported a number of stories that relate to it, from the rise of Uber and Lyft to the push by some port truck drivers to be classified as employees rather than independent contractors by the companies they drive for.
I've worked full time for the same company for the last 12 years, so my own professional exposure to the gig economy is limited. But clearly, more people are turning to "gigs" — freelancing, working as independent contractors — to make a living, or at least some extra money.
Who are these people, how many are there, and why have they chosen "gigs" over steady employment? My attempt to answer these questions has put me in touch with some smart and interesting people.
