Okay. All good points. Here is another question...

They called me this morning to come meet with one of the other doctors on Monday. The time they want me to come is not my usual lunchtime so I will have to make explanation as to why I am changing my lunchtime for the second time in just a few days. Do I go ahead and tell my supervisor I'm going for a job interview? It wouldn't be an untruth to say it was a surprise opportunity, and she is aware of some of the frustrations I have had here.
