In the framework of its 2022-2023 work programme, Labour Law Community – LLC has initiated a cycle of seminars – Early career seminars on COmparative Labour Law – ECOLL – dedicated to early career scholars, including PhD students. ECOLL is based on two main ideas: believing in the critical virtues of the comparative method, the seminars will resort extensively to a comparative law methodology. On the other hand, while being dedicated to early career scholars, ECOLL aims to nurture the dialogue between the different generations of scholars. The first seminar took place on 20-21 May 2022. The video presents the first session about the theoretical background of the seminar, that was open to everyone.
