Working Groups

WG 1 – Survey

The goal of WG 1 is to collect and provide data on Leibniz PostDocs to get an idea about who Leibniz PostDocs are and how they are doing at their Leibniz Institutes. We regularly administer surveys, analyze and publish the results, as well as present the results in the Leibniz Postdoc Network, at meetings, or conferences.
In summer 2020, we administered the First Leibniz PostDoc Survey to examine employment histories, future career plans and training needs, as well as challenges concerning work-life balance or relationships with superiors. Some of the questions were specifically related to the situation of Leibniz PostDocs with an international background. The results of this survey are available on our website (see Resources).
In winter 2022/23, we run the Second Leibniz PostDoc Survey that aims at providing an update on many aspects asked in the first survey. Additionally, we included new topics in the survey, targeting aspects like working remotely or mental health. With all these questions, we hope to provide evidence on topics that currently matter for Leibniz PostDocs.
