I will first review basic aspects of supersymmetry breaking and gauge mediation. Then I will consider a scenario with two susy breaking hidden sector which decouple when their respective couplings to the visible particles are switched off. In such a scenario one expects to find two light fermions: the goldstino and the pseudo-goldstino. I will analyze the mass induced to the pseudo goldstino by radiative corrections in a general gauge mediation framework. I will finally discuss some of the phenomenological consequences.
