The CJEU’S Matzak judgment raises diverse and important questions concerning (not only) working time regulation in the European Union. The present special issue sheds light on some of these questions, more specifically with regard to the Working Time Directive‘s personal scope as well as the notions of working time and rest time under EU law. The Directive’s scope is linked to the concept of worker and the criteria to construct it and, in the context of the Matzak case, leads to interesting questions about the position of volunteers in EU law and the problem of concurrent contracts. In this respect, exploring a purposive approach attending to the health and safety aims of the Directive may be fruitful. The boundaries between working time and rest time are far from clear, especially in situations of stand-by and on call time. Here the proposal of an intermediate category related to the idea of quality of rest time is discussed.

欧盟法院对Matzak的判决：工人的概念以及工作和休息时间的模糊边界

CJEU的Matzak判决提出了有关（不仅是）欧盟工作时间规定的各种重要问题。本期专刊阐明了其中一些问题，尤其是有关《工作时间指令》的个人范围以及欧盟法律规定的工作时间和休息时间的概念。该指令的范围与工人的概念以及构造工人的标准有关，在Matzak案的背景下，该指令引发了有关志愿者在欧盟法律中的地位以及并发合同问题的有趣问题。在这方面，探索符合该指令的健康和安全目标的目的性方法可能会富有成果。工作时间和休息时间之间的界限远未明确，特别是在待机和通话时间的情况下。
