Welcome to the Institute

for Labour Law and Industrial Relations

in the European Union

THE INSTITUTE

The employees of the IAAEU research the underlying economic and legal conditions for labour in a constantly changing European society. Our task is project-related research, which is interdisciplinary, socially relevant and receives international attention. The goal is to influence the public discourse with scientific findings and thereby improve the conditions for labour and industrial relations. In that light, the institute understands itself as an initiating force for other researchers and for the region. The IAAEU was founded as a public law foundation in 1983. The institute is financed by the German Federal State of Rhineland-Palatinate and is also a scientific institution attached to Trier University. It is located on Campus II of the University.

Research at the IAAEU takes place under a tight cooperation between the two chairs of the co-directors Prof. Dr. Dres. h.c. Monika Schlachter (International and European Labour Law and Civil Law) and Prof. Dr. Laszlo Goerke (Business Administration – Personnel Economics). Furthermore, the institute maintains an extensive library with a unique collection of works pertinent to labour law, industrials relations, particularly industrial relations between member states of the EU, and personnel economics.

New publication in Oxford Economic Papers

New study by Laszlo Goerke and Sven Hartmann on "Habit Formation and Trade Unions," published in Oxford Economic Papers. The assumption that preferences are separable over time, e.g. that the evaluation of today's income does not depend on past income levels, has long since been an important assumption for economic analyses of human behaviour. Empirical findings, however, suggest that an individual’s well-being is not only determined by their current wage, but is also influenced by comparisons with past income. In many cases, employees prefer an increasing wage over time to a decreasing income, even if the sum of all payments is the same in both cases. Accordingly, preferences that are co-determined by comparisons over time have an impact on the behaviour of individuals, as has already been shown for many economically relevant situations. Consequently, they also influence the functioning of labour market institutions.

New publication by staff of IAAEU on the determinants of job satisfaction

Suppose, you join a club or become a member of an organisation which represents your interests. Then one can expect that you are more satisfied than before joining. This basic idea has led to the hypothesis that individuals who are members of a trade union can be expected to exhibit a higher level of job satisfaction than comparable non-members. Strikingly, early empirical analyses of the relationship between trade union membership and job satisfaction for Anglo-Saxon countries have shown the opposite, namely that union members are less satisfied. This apparent puzzle has sparked a debate, which has continued for almost half a century and become livelier again in recent years.

A study on job security and job retention in collective agreements and company agreements was published

On 28 June 2022, the Hugo Sinzheimer Institute (HSI) of the Hans Böckler Foundation published a study on job security and job retention in collective agreements and company agreements, in which Prof. Dr. Dr. h.c. mult. Monika Schlachter and Dr. Thomas Klein were among the contributors. Among other things, the study examines the relationship between collective bargaining autonomy and entrepreneurial freedom, and concludes that, contrary to the point of view sometimes expressed in the literature on this topic, location and employment guarantees as well as investment commitments, can also be agreed upon by collective agreement and, if necessary, enforced through the use of industrial action.

TriECON workshop series leaves the virtual world

For many years, the IAAEU has organised workshops on staff members' current research, and has invited researchers from all over Europe to present analyses related to these topic. The workshops provided a forum for intense discussions and the exchange of ideas.
