Assistant manager

Hi everyone,

I am wondering I am being offered a position as an assistant manager in an primarily outpatient department(GI). This role is new to the hospital system. The number of direct reports are 7RN, 1 secretary, and 2 cna. my hesitation is the role is new, what if it is identified as not needed in 6 months then what. The director explains the need for the role is due to the fact she is at another site in the system 3 days a week. i am just unclear in this instant whether to leap on faith or fear the unknown. I really would love this opportunity to learn some management skills but unsure if that is exactly how i will be used. Her description of what this role entails is vague. It seems for the most part I will have to act as charge nurse to make sure add on cases are being done, and patients are moved in a timely fashion.The administrative component will entail payroll, disciplines and up keep of the department. The other side is relieving nurses when busy for lunches and breaks, which I don't mind. I am just concerned about future of the position. Any insight is helpful
