how to quit a job? dental assistant

Breanna
Ok ladies I really need some help here. About 8 months ago I started my career as a dental assistant. The office im at was never really a place I liked going to. The staff was always rude and never made me feel comfortable. I recently found a new opportunity at a different office where I went to school with a few memebers of the staff so I know I'll be welcomed there. Anyway. I've never formally quit a job and I'm not sure how.
