Controversy on the sanctions practice
From 2005, Hannemann worked for the Job Center Hamburg-Altona. According to media articles, she refused to issue s in case of rule violations over several months. Hannemann denies these accusations and claims to have only withdrawn sanctions in individual, justified cases. Whether to issue a sanction or not lies within the discretion of the case worker. Furthermore, Hannemann criticized how case workers at the Job Center deal with recipients of benefits of Hartz IV and applicable guidelines. For these reasons, she was suspended by the Job Center in 2013 and was banned from entering the premises. Hannemann was offered a position in the district office of Eimsbüttel, which she declined. Instead, she sought reinstatement as a job placement counselor at the Job Center. Her emergency appeal was rejected by the labor court on July 30, 2013. The main proceedings were originally scheduled for July 11, 2014, but the court cancelled the day before because the city of Hamburg revoked her assignment to the Job Center in order to employ her in a different position. Hannemann's attempts to reverse the revocation of the secondment were unsuccessful. In December 2014 Hannemann agreed to a settlement and has worked for the integration office since. Over 16000 people signed an online-petition demanding that her employer withdraw the disciplinary actions against Hannemann. Hannemann was the first employee of a German Job Center to publicly criticize the labor market policy of Agenda 2010. She claimed in her Altona-Blog and many presentations and interviews that "support and demand" — the proclaimed goal of the Hartz-concept — long since gave way to technocracy. Hartz IV fails to offer a perspective for unemployed people to reenter the labor market, but instead applies sanctions to deny their benefits. During the labor court trial, the Federal Labor Agency declared that the abuse described by Hannemann does not exist and that she was endangering thousands of Job Center employees. Instead, they maintained, she simply chose the wrong job. Hannemann objected and claimed to be able to prove her allegation with documents. On November 20, 2013 Hannemann's petition "Arbeitslosengeld II - Abschafffung der Sanktionen und Leistungseinschränkungen " was published on the petition website of the German Federal Parliament. 50,000 signatures were necessary to reach the quorum. This goal was reached already on December 16, 2013. On March 17, 2014, the petition was dealt with in a public session of the petition committee of the German Federal Parliament.
