Dependent on your faculty position, location, population, and program, you will find wide variation in responsibility and time committment. However as a former manager, wouldn't change a thing!

Paperwork is an evil whether you are didactic based or a clinical educator. Numbers of students in the program also is a factor (I am employed as faculty in a diploma program which admits 100-120 biannually with a current student census of over 420 total throughout the program. The program is 48/52 weeks annually.) Students have clinicals and classroom theory every week throughout the course of the program. Our faculty are all MSN prepared and some beyond, with a student mix of high school and adult learners.
Having been a clinical as well as didactic instructor, the preparatory work required is more involved in the classroom, as it should be. I do not use test banks but develop my own test questions as do most of our faculty. I maintain clinical preparedness by working casually in my system hospital to maintain my skills and certification in my specialty.
Most gratifying? The abilty to shape the minds and hearts of the future leaders (and my caregivers!) to the best career path option. So many advances, too numerous to share. All the best in your decisionmaking!
