Slacking "Sarah"...

I swear that "Sarah"does less and less work now that her days at the library are growing shorter. Today I was left alone with her in the department while our Department Head went to the Adult Librarian's meeting and "Julia" went to cover their reference desk. The minute I sat down at one of the computers at our desk she walked into the office, sat at her desk and began to read a book. She didn't come out of the office the whole time I was out on the desk -- Which was for over an hour. But the minute our Department Head came back she was out at the reference desk pretending to do shit while we all know she was really looking at random crap on the internet. I cannot wait for this bitch to be gone.
