In this talk the following question is addressed: are internal symmetries necessarily restored at high temperature in supersymmetric theories? Contrary to the general belief, we argue that the answer is no when systems possess a net background charge. Our findings are exemplified on abelian models, for both cases of global and local symmetries and possible cosmological implications are also discussed.
