For me, I guess going above and beyond the call of duty is really about going all out to get a job done properly. For example, I once worked on a large team project where I could tell that one of my colleagues was struggling with her task. To some extent, my work was dependent on hers, and it's probable that had she delivered late, I may have been forced to as well. I approached her discreetly over lunch and offered to stay late and help her out. She couldn't thank me enough, we worked through the night, and in the end, she was able to deliver on time, and so was I.
