Sorry you're having such a tough time..Is it just the Ortho service you are having difficulty with? Ortho can be tough, especially for someone new to the OR..Some people are very good at their jobs, but don't remember what it was like when they were new. Expecting you to anticipate every little thing right now is a bit harsh-anticipation comes with experience as does speed. Even though this person is friendly with the boss, I still think you should approach your boss about this. There is a professional, classy way to do this. Tell her that you like the OR and want to learn but that you may need a little time. Ask her for specific things to work on and let her see that you are trying to fix things. The checking of the case cart is actually a very good habit to get into, especially if you didn't pick that case yourself. After all, it is you who will be in trouble if you don't have what you need. There are instrument books that may help you learn the instruments. But when it is all said and done, you can only do so much..All of this is not your fault. It sounds as though this workplace needs a refresher on how to properly orient new staff. I'm pulling for you. Good luck!
