S. aureus has an intrinsic rifampicin resistance mechanism! See the recent study by M. Otto's lab with important clinical implications:

Export by a quorum sensing–controlled drug exporter underlies rifampicin’s strong activity against staphylococcal biofilms
Rifampicin is more effective against biofilm infections because it targets biofilm-forming mutants that are highly resistant to other antibiotics.
