WVUH......any info???

Hi! I graduated from school with my ADN in May and am currently undergoing orientation at Ruby for a GN position. I must say I am feeling VERY overwhelmed... but also excited! Does anyone here have any input as to what WVUH is like as an employer? Have they been fair? I heard that on a med-surg floor that it is realistic to expect to be on your own after 3 or 4 weeks of precepting. I am also thinking about re-enrolling in school this year to get my BSN, but am scared to ask them to accomodate my schedule...I may have to cut back my hours to do this. I don't want to ask too much since I am new. Does anyone know how often raises are given and the percentage a raise normally is? Wondering if it is performance based or across the board? I had 2 other job offers but chose Ruby because it has such a wonderful reputation...I am just hoping I didn't bite off more than I can chew!!!! Thanks in advance for any information you might have!
