In developed countries, the food superstore or hypermarket has become the dominant mode of food distribution; and their success has transformed the retail sector. But each new store has changed the employment regime of the stores they replace. For retailers, labour is a major cost; with opening hours being extended, and consumer demand patterns changing, one solution has been the use of part-time labour. Extensive use of such labour characterises British food retailing for example whereas it is less common in France. This book examines the reasons for such differences, and the potential which management and employees have within the operation to manage working time to their benefit. This book makes use of a four country research programme, covering France, Germany, Great Britain and Japan. Investigations and interviews at store, company and individual levels paint a picture of working times in the sector and in each of the countries. The volume provides some explanations for national differences as well as the similarities; supply and demand issues, as well as societal and social backgrounds. Large format food retailing is a major force in each country, employing millions in many different situations and conditions. This book suggests opportunities for retailers and employees to better manage their situations.
