Definition
A "zero-hour contract" is a type of
contract
A contract is an agreement that specifies certain legally enforceable rights and obligations pertaining to two or more parties. A contract typically involves consent to transfer of goods, services, money, or promise to transfer any of thos ...
between an employer and a worker according to which the employer is not obliged to provide any minimum working hours and the worker is not obliged to accept any work offered.
The term "zero-hour contract" is primarily used in the United Kingdom.
The employee may sign an agreement to be available for work as and when required, so that no particular number of hours or times of work are specified.
Under U.K. law a distinction is drawn between a "worker" and an "employee," an employee having more legal rights than a worker.
Whether a person working under a zero-hour contract is an employee or a worker can be uncertain; however, even in cases where the plain text of the zero-hour contract designates the person as a "worker" courts have inferred an employment relationship based on the mutuality of obligation between employer and employee.
Zero-hours contracts provide basic social security benefits, including maternity/paternity pay, holiday, and health insurance. A zero-hour contract may differ from
casual work
Contingent work, casual work, gig work or contract work, is an employment relationship with limited job security, payment on a piece work basis, typically part-time (typically with variable hours) that is considered non-permanent.

zero-hour contracts were sometimes used to "clock-off" staff during quiet periods while retaining them on site so they could be returned to paid work should the need arise. The National Minimum Wage Regulations require that employers pay the national minimum wage for the time workers are required to be at the workplace even if there is no "work" to do. In the past, some employees working on a zero-hour contract have been told that they are required to obtain permission of their employer before accepting other work, but this practice has now been banned under UK legislation enacted in May 2015.

estimated that there are over 900,000 workers on zero-hours contracts (2.9% of the employed workforce), up from 747,000 the previous year, with over 1.8 million such contracts (as some people may have more than one contract),
with a further 1.3 million where no hours were worked. Some commentators have observed that the number of such contracts may be under-reported, as many people may be confusing them with
casual employment, and may not be reporting them as temporary. The Chartered Institute of Personnel and Development (CIPD), based on a poll of 1,000 workers, reported in August 2013 that as many as 1 million workers in the United Kingdom, 3–4% of the workforce, work under the terms of a zero-hour contract.
Based on a survey of 5,000 of its members,
Unite, Britain's largest labour union, estimates that as many as 5.5 million workers are subject to zero-hour contracts, 22% of those employed privately. The survey, conducted by Mass 1, showed that zero-hour contracts were more prevalent in northwest England, among young workers, and in agricultural work. Often workers said that
holiday pay was illegally denied,

as well. The
National Farmers Union, which represents farmers, supports zero-hour contracts as offering needed flexibility for tasks such as harvesting.
According to the CIPD research, about 38% of those employed under zero-hours contracts considered themselves to be employed full-time, working 30 hours or more a week. While 66% of those on zero-hours contracts were happy with the hours they worked,
16% felt they did not have an opportunity to work enough hours. About 17% of private employers used zero-hours contracts while they were used by 34% of non-profits organisations and 24% of public employers. Zero-hours contracts were frequently used in hotels, catering and leisure (48%), education (35%) and healthcare (27%).
For domiciliary care workers the incidence was reported to be as high as 55.7% of all workers during the period 200812.
In 2011, zero-hours contracts were in use in many parts of the UK economy:
* in the hotels and restaurants sector, 19% of all workplaces (up from 4% in 2004)
* in the health sector, 13% (up from 7%)
* in the education sector, 10% (up from 1%)

The Workplace Employment Relations Survey conducted by the government of the UK in 2004 and 2011 shows that the proportion of workplaces that have some employees on zero-hours contracts has increased from 4% in 2004 to 8% in 2011. The survey found that larger companies are more likely to use zero-hours contracts. 23% of workplaces that have 100 or more employees used zero-hours contracts in 2011, compared to 11% of those with 50–99 employees and 6% of those with fewer than 50 employees.
Controversy
In the UK, zero-hour contracts are controversial. British business leaders have supported them, stating that they provide a flexible labour market. It is argued they may suit some people such as retirees and students who want occasional earnings and are able to be entirely flexible about when they work. It has been reported that 60% of people on zero-hour contracts are happy with the hours they work. Trade union groups and others have raised concerns about exploitation and the use of such contracts by management as a tool to reward or reprimand employees for any reason, meaningful or trivial. They also raise concerns about how workers can adequately assert their employment rights or maintain decent employment relations. A Channel 4

used "controversial" zero-hour contracts as a tool to reprimand staff.
Workers subject to zero-hour contracts are vulnerable to exploitation as they may be denied work at any time for any reason, including declining to respond to a demand to work. A refusal to work in any one instance for any reason can result in a prolonged period of lack of work. Due to the uncertainty of the workers' schedules, zero-hour contracts present problems for workers with children due to the difficulty of arranging child care. The rapidly growing use of zero-hour contracts was the subject of a series of articles in late July 2013 by ''The Guardian

In 2016, several UK chains that had been using zero-hour contracts announced that they would phase them out during 2017. These included Sports Direct and two cinema chains, Curzon and Everyman. However, Cineworld, another leading cinema chain that also owns Picturehouse, has come under scrutiny for continuing to use the contract format, with the Ritzy living wage protests at London's Ritzy Cinema especially prominent.
In 2020, a campaign called Zero Hours Justice was set up. Led by Ian Hodson, president of the Bakers, Food and Allied Workers Union and backed by Julian Richer, it was launched with the aim of ending zero hours contracts.
