4.7m people in the UK work in the gig economy

"Last month, new data on the U.K.’s gig economy surfaced from the University of Hertfordshire, concluding that the number of gig workers in Britain has more than doubled in the last three years, now reaching 4.7 million professionals.
Experts say the explosion of technology platforms like Uber and Deliveroo ushered in waves of opportunity for professionals to have greater control over when, where and how they work. The U.K.’s Trades Union Congress, however, sees this surge in gig workers from a different angle."
