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.
