Human Factors
The aft Flight Attendant; appeared extremely fatigued. Upon completing her cabin service in the main cabin she put the cart away then proceeded to row XX and slept in seat XX for remainder of the flight until I made the before landing PA announcement. During the time she was gone; I was taking care of my first class passengers and trying to keep watch on the main cabin. After making my before landing announcement she did the cabin check in the main cabin as well as collect trash then she sat in the aft jumpseat for landing. I believe she was extremely fatigued or very ill.
Flight Attendant reported that another Flight Attendant experienced illness or fatigue; causing her to be unable to perform her duties.
