Low quality, unproductive jobs trap workers in low pay and harm the rest of the economy, a top economist has warned.

Unemployment has crashed in recent years, removing much of the problem of joblessness - but that does not mean there are no more improvements that can be made, according to Matthew Taylor, chief executive of the Royal Society for the Encouragement of Arts, Manufactures and Commerce (RSA) and head of a Government review into the gig economy.

Too few jobs offer a feeling of “genuine flexibility, being valued and respected, learning and growing, having voice and autonomy, feeling work has a meaning and purpose,” he said at his annual lecture.
