Starting from the assertion that crisis is part of the essence of labour law, this volume brings together researchers in the field who accepted the challenge to critically reflect on this branch of the discipline. As the COVID-19 pandemic has had a global impact, labour law across the world must come to terms with a new reality. In this context, it would be prudent to adapt to new circumstances by taking known paths.To this end, this book reflects on what effectively constitutes labour law, considering questions which are not usual within labour law. Insights from philosophical, sociological and even economic standpoints are mobilised to reconcile the past with the future of labour law.
