I think that answer necessarily changes throughout the course of each career in our lifetime. I have changed careers a couple of times and my feelings have fluctuated over time. I recently resigned for several different reasons. However, I have to admit that I disliked my employer far more than I dislike my job although the two are necessarily tied somewhat. With more time to comtemplate, I am also realizing that I don't know whether I want to continue on this career path, but one of the obvious issues is the ability to earn a reasonable income doing something else.
