Abstract
It is generally believed that internal symmetries are necessarily restored at high temperature in supersymmetric theories. We provide simple and natural counterexamples to this no-go theorem for systems having a net background charge. We exemplify our findings on abelian models, for both cases of global and local symmetries and discuss their possible implications.
