Zero Hour Contracts

A zero-hour contract is a contract of employment used in the United Kingdom which while meeting the terms of the Employment Rights Act 1996 by providing a written statement of the terms and conditions of employment contains provisions which create an ‘on call’ arrangement between employer and employee. It does not oblige the employer to provide work for the employee, nor does it oblige the employee to accept the work offered. wiki

Zero-hour contracts are used extensively in the private, non-profit, and public sectors in the United Kingdom. Companies using such contracts include Sports Direct, J D Wetherspoon, Cineworld,McDonald's, Burger King, Hovis (owned by Premier Foods), Starbucks, Boots, and Amazon.
