because you will get called at odd hours and ealier than you expected!...new learning. Must admit as I write this evening, I am fatigued and stressed for a number of reasons, including my casual coverage at the hospital in a position ( CCU, ER & a family medicine team ) with a new learning curve that needs full time coverage and I am available only part time. Eating lunch at 4:30 PM reminded me that food intake is important. Co-workers were helpful when I put out a voicemail for help on one situation I could not get to and I had to laugh when I got a report later that the social worker who came was  "a short lady with brown hair and glasses"...actually a description that could have fit a number of us! There are factors beyond my control and not my responsibility as a casual, such as a change in managers and reorganization of teams, but I still feel rather caught when I cannot do all I want to do or think I should. I love the flexibility of doing casual work whether at the hospital or when in the north, and generally one does not get involved in the administration politics, but there are times when being short term is frustrating....I just hope that I can leave my work stints with as thorough a job done as possible, so the next worker can pick up with ease. Co-worker told me I do "ducky" work so I'll hold on to that one!
