We study the dynamics of quantum steering between two-mode Dirac fields in the non-inertial frame and interact with two independent thermal baths. Special attention is paid to the distinction of the two effects induced by Unruh radiation and thermal baths. We find that both the two effects reduce quantum steering and induce generally steering asymmetry. However, different cooperative effects arise: For the decays of quantum steering itself, the two effects are always constructive; for the asymmetry of steering, however, they have different behaviors depending on the feature of thermal baths and are generally destructive.
