The book discusses how labour law and welfare systems will be affected by the ongoing transformation of work. The first section considers demography from two different perspectives. On the one hand, it focuses on chronic diseases and their impact on work, emphasising the role and the regulation of welfare systems. On the other, attention is given to youth unemployment and to those forms of employment which might have an impact on young people. Section II touches upon the relationship between the environment and industrial relations, while the third part broaches the topic of the impact of technology in the context of the Fourth Industrial Revolution, also known as Industry 4.0. As such, this volume provides an exhaustive picture of the changes currently underway, considering all the aspects which will affect work now and in the future.
