In today’s globalized labour law, where borders, especially within the European Union, seem to be increasingly blurred, cross-border situations are becoming more common. Due to digitalisation and technology, which is evolving at a rapid pace especially in the present situation, working abroad can now be carried out without the worker actually moving away from his desk, namely not physically entering another country. In view of this, the topicality and exciting nature of the processed topic can hardly be questioned. Following a holistic approach, the reviewed book guides the readers with unique detail and provides them with a sure point of reference on the swampy ground of the posting, which is surrounded by many challenges and conflicts of interests. In our review, we will describe and evaluate the content of the monograph along these sure points of reference.
