Congrats, Katherine! I would definitely keep a journal of accomplishments that you done in this job, so that when it comes time for reviews and/or promotion, you won't have to rely on your memory, you'll have it written down in a journal regarding the specifics of a particular situation (like the one you outlined above) that occurred, as well as the date/time and who was involved and the outcome. It will serve you well, as well as CYA (Covered Your A$$).
