Work at Canadian Blood Services

I am a RN who has worked for five years on Medical Wards and I am looking for a change. I hate night shifts, so am looking for days and evenings. I was offered a job on a general surgery ward and also a job at Canadian Blood Services and I am torn over which one to pick. Just wondering if anyone out there has worked for blood services and how they liked it? Is it the type of job that would be repetitive and boring or is it challenging and stimulating? Any advice appreciated!
