We investigate the dual roles of electron electron interactions and site-diagonal disorder in a strange bad metal. Saturating-and insulating-like resistivity observed in the non-magnetically ordered phase of tetragonal FeTe are shown to be driven by the interplay between multiband effects and iron-d shell band-filling. Incorporation of site-diagonal disorder promotes weak electronic delocalization and metallicity in tetragonal FeTe. The correlated electronic structure we derive is promising in the sense that it leads to results that might explain why moderate disorder can generate nearly linear resistivity dependence in strange metals.
