Okay, here's my situation. I work for a Dr's office and 2 days a week they come from their base office to my town and set up shop. I work there when they come to my town, Th and Fri. When they come on Thursdays it's 1 Dr and 1 nurse. On Fridays it's another Dr and the nurse alternates between 2. And there's one lady that trained me in my position that I'm close with. So in total, out of the office of like 15 people, I work with 6 regularly. However, I call the other office and talk to almost everyone everyday (to make appointments, help, etc) as well. So it's not like I don't talk to them or that I've never met them (I've filled in at the base office before for them). My question is, do I need to invite the people in the base office if I don't usually work with along with the people I see every week, or am I okay to just invite the people I work with each week? Any help/ideas/suggestions are welcome! Thank you!
