She sounds somewhat like a private contractor or consultant of some sort,she has to file her own taxes. It sounds like it can get more involved and cost more when she has to file taxes with her accountant. She can contact some local labor place or ask any familiar one with taxes and ask them what the deal is. If she not paid salary they must keep some track of her hours to know how much to pay her each week. Something sounds fishy,she should right down her hours in a notebook and safe all her pay checks.
