Book excerpt: In recent years, new and more intrusive surveillance technology has found its way into workplaces. New medical tests provide detailed information about workers' biology that was previously unthinkable. An increasing number of employees work under camera surveillance. At the same time, computers allow for a detailed monitoring of our interactions with machines, and all this information can be electronically stored in an easily accessible format. What is happening in our workplaces? Has the trend towards more humane workplaces been broken? From an ethical point of view, which types and degrees of surveillance are acceptable, and which are not? From a policy point of view, what methods can be used to regulate the use of surveillance technology in workplaces? These are some of the questions that have driven the research reported in this book. Written by an interdisciplinary group of researchers in Computer Ethics, Medical Ethics and Moral Philosophy, this book provides a broad overview that covers both empirical and normative aspects of workplace privacy.
