Translate the following English sentence to French:
"Anyone who would jeopardise production at this steelworks on principle, by demanding the return of the aid that was granted at the time, would not just place the steelworks itself in jeopardy but also one of the region' s employers that small and medium-sized enterprises are, of course, dependent on too."
Celui qui menace, en principe, la production de cette usine en exigeant le remboursement des aides accordées à l'époque ne menace pas seulement cette aciérie mais aussi un employeur de cette région dont dépendent bien entendu des petites et moyennes entreprises.
