B erlin (dpa) – The Union rejects SPD leader Andrea Nahles' demand to refrain from penalties for young Hartz IV receivers. That would be impossible, said the vice-president of the Union faction, Hermann Gröhe, the newspapers of the Funke-Mediengruppe. "In cooperation with Hartz IV, cooperation obligations have also been included to find work again." Young Hartz IV recipients can be punished harder for violations of the rules in force than parents. Already at the first violation, which goes beyond a registration warning, the entire performance can be blocked.
