The IAAEU started 2019 off with another exciting lecture for students, staff members and other interested persons. Lawyer Antonius Allgaier (Industriegewerkschaft Bauen-Agrar-Umwelt) gave a lecture on 16th January 2019 regarding "Collective Agreements for Sole Proprietors". By doing so, he presented vividly which challenges the growing number of sole proprietors in the construction industry entails. He especially discussed the issue of training cost levy and the respective BAG verdict from 1st August 2017. As usual, the lecture closed with an open discussion that covered unanswered questions.
