Five years ago, “zero hours” contracts came to the attention of the national media. While there is no one type of “zero hours” contract, in all cases workers receive no guaranteed weekly hours or income. Workers are paid only for the actual hours worked, and the employer is under no obligation to provide any work. Their use by employers in very many sectors of the British economy has mushroomed in recent years. In 2006, possibly 0.5% of the workforce had “zero hours” contracts (130,000). According to the Labour Force Survey, 901,000 people (representing 2.8% of all workers) were on contracts that do not guarantee work in December 2017.
