The FDGB was closely integrated into the country's power structure, and after the 3rd FDGB Congress, which took place in 1950, Groh-Kummerlöw became responsible for the organisation's Worker Supply Department. The issue of worker supply was important nationally in the context of a desperate shortage of workers, following the large-scale slaughter of the war and the continuing haemorrhage of working age citizens across the still relatively porous border to West Germany. For the Trades Union organisation improvements in social policy were central to the Worker Supply Department. In 1952 the departments at the FDGB were reconfigured and she also took over from responsibility for Social Security matters. In 1957 Groh-Kummerlöw switched, becoming Secretary of the Central Committee for Industrial Unions in the local economy, before further promotion in 1958 which was when she became Secretary of the FDGB group in the national People's Chamber.
