Every year the Adecco Group Switzerland publishes both a comprehensive and a short study about skills shortages in Switzerland, in collaboration with the Swiss Job Market Monitor (SMM) and the Institute of Sociology at the University of Zurich. These scientifically substantiated skills shortage studies reveal the occupations for which the number of vacancies is particularly large compared to the number of job seekers, as well as the occupations for which this number is particularly small. In addition, the collection and comparison of data over many years makes it possible to identify increases and decreases in skills shortages for each occupation.
