Societal and economic developments, such as the need for increased flexibility by both employers and workers, have resulted in the emergence of new forms of employment across Europe. These have transformed the traditional one-to-one relationship between employer and employee. They are also characterised by unconventional work patterns and places of work, or by the irregular provision of work. However, little is known about these ‘new forms of employment’, their distinctive features and the implications they have for working conditions and the labour market. To fill this knowledge gap, Eurofound conducted a Europe-wide mapping exercise to identify the emerging trends. This resulted in the categorisation of nine broad types of new employment forms. On the basis of this, the available literature and data were analysed; 66 case studies were also conducted and analysed to illustrate how these new employment forms operate in Member States and their effects on working conditions and the labour market.
