Owen Smith, contender for the Labour leadership, has today flagged how the UK is failing in terms of workers' rights. One area he picks up on is the use of zero-hours contracts, but how does that sit in a world where some people really value the flexibility of an 'Uber' like contract - the ability to determine your own hours to suit your commitments? If we clamp down on the use of these contracts too heavily, surely some people will lose out - those who want to determine their own working pattern and have a portfolio of work to pick and choose from when they choose.
