The massive YSO HH 80-81 is deeply embedded in a giant molecular cloud. It has bipolar outflows that are well characterized through radio imaging and spectral line measurements. At radio wavelengths the source has a morphology with three well-defined hot spots. The central, thermal one, is associated with the protostar. The other two, of non-thermal nature, are thought to be the results of the interaction of the jets with the ambient medium. Very recently Carrasco-Gonzalez et al. (2010) have detected non-thermal polarized radiation from the jets. The particles responsible for this emission, we argue, should be locally accelerated. We suggest that magnetic reconnection might play a major role in the generation of such particles. We propose a specific model for the origin of the non-thermal particle electron injection and we discuss the broadband electromagnetic emission expected for these jets.
