Fratzscher, President of the German Institute for Economic Research, criticized the reform package for favoring corporate relief at the expense of employees, warning of an unfinanced tax reform that could exacerbate the national deficit. Conversely, Fuest of the ifo Institute praised labor market flexibility measures but criticized the income tax reform for increasing burdens on medium-sized enterprises. Labor unions, including the DGB, acknowledged positive signals for employment but expressed concerns over expanded fixed-term contracts. Opposition parties condemned the reforms as inadequate, particularly regarding the handling of artificial intelligence impacts and the proposed elimination of telephonic sick leave, which they argue undermines trust in citizens.
