centennail gmc scott peters timdonnelly slander discrimination las vegas, Nevada

well i started working for centennail gmc on 6-25-12. in november we had a conflict over a commision so i went to the hr department. after i went there scott peters said all they will do is give it to and scott will discard it later. that tim donnelly the gm came up to me and said if i were you i would never ever go to hr about any thing infact he said i should never ever even go close to that building. well than on2-16-13 when i came in to work i was geeted by scott peters he said me and him were driving around town smoking meth all night and called me a druck driver and he was going to come over to my house and take every thing away from me. well thats nothing but slander. i sure hopes he brings the police over to my house so they can take a hair sample
