We discuss the semiclassical scattering problem for massless matter coupled to Rarita-Schwinger field in four dimensional Minkowski space. We rewrite the soft gravitino theorem as a Ward identity for the S-matrix and discuss the relationship of corresponding symmetry charges to new asymptotic fermonic symmetries of massless Rarita-Schwinger field.
