Flexibility becomes increasingly the crucial success factor. This is the result of a current survey on small and medium-sized enterprises in Germany. More than a quarter of the participants indicated that flexibility was their most important business goal. What this result means for the personnel policy of a company and in the end for its employees is the focus of this article. The here presented survey is part of the BMBF project “FlexPro” that investigates different strategies of internal flexibilization as well as determinants of using external workers, especially temporary agency workers.
