I honestly do not know how or why he was authorized to work in this job field/MOS/rating. He has absolutely ZERO office skills; no telephone skills, no computer skills. Helen Keller could type faster than him. He can't even take a phone message right. The Chaplain of the Marine Corps called, Admiral Burt, and my co-worker answered the phone. Thirty seconds later, he hands me the phone. The Admiral says, "You really need to work on his phone skills." I asked him to replace all of the toner cartridges in the laser printer. Well, he did but with old, empty cartridges. Then I asked him again. He swapped in even older cartridges. I mean, there's a little display screen on the printer that reads CARTRIDGES EMPTY! What more do you need? As a SNCO, I've tried to train this guy but nothing seems to work. I've given him typing tutors, MS Office tutorials, and even gone as far as to stand at his shoulder while typing up something as simple as a routing sheet. I can't even leave my office for a day. The final straw came last week. I spent an hour on a task listing, giving him EVERY DETAIL POSSIBLE. The who, what, when, where, why and how regarding everything I needed him to do while I was TAD to Korea. He couldn't do it. My supervisor (E8) had to step in and finish the task list. How freaking embarrassing. I honestly do know what else to do. I can't help someone that can't be helped. How do you help someone that can't even find the SEND button in MS Outlook to send out emails?
