Depending on who you ask, zero-hours contracts are either a vital facet of a modern economy, suiting both employee and employer, or a symptom of a race to the bottom in an era of lessening worker power and job security.
What's certain is they are increasingly prevalent. Figures from the Office for National Statistics indicate that 582,935 UK workers were on these contracts in 2013.
