New people are hard

Have you ever had someone you work with be a total slacker? I can relate to that one. We have a new person in the office who has been there before, left and came back recently, into a new position. I understand that this person doesn't know the same stuff that we other secretaries know, but she was there a week and learned some of the stuff. Like answering the phones, come on man. When you have other people in the office who are totally busy with other stuff, at least answer the f**ing phones!
Can you stay at your desk long enough to help us??? What the hell can she be thinking? I hope the week gets better.
