Missing workers

I had last Thursday & Friday off on holiday, so when I got in on Monday I asked if I had missed anything. "Yeah, you missed loads", was the comeback. I thought they were being sarcastic, but as it turned out it was true.
Apparently on the Thursday, Jim (the quiet one) went missing at about 10.30 in the morning. Only it wasn't until about 2.30pm that anybody noticed.
He's usually quiet, so you imagine he is just working away quietly, as he does. Then he normally goes home for dinner for an hour or so, not returning until 1.10 usually. Usually you can set your clock by him.
Apparently one of the girls had heard him take a phone call, which is unusual in itself, then he just left without saying a word. Ned noticed he wasn't in at 2.30 and asked where he had gone. Nobody knew, so Ned got worried in case he had been in an accident on his way to or from dinner. He tried ringing the numbers we have as contacts for him, none of which got an answer. So they had a big conflab, and Ned and one of the other managers decided they should go and do a home visit, as he didn't live far away anyway.
As it turned out, he was at home, fine. His sister had rung him to tell him that his dad had been in some kind of traffic accident, and she had called him a taxi, or was in a taxi, waiting downstairs to take him to the hospital. His dad was okay. I couldn't find out why Jim had stayed at home instead of coming back to work. He reconned that he didn't tell anyone because the taxi was waiting for him. Also I'm not sure if he took the Friday off work too.
When Ned got back to the office his boss had asked if Jim was going to make up the time or was taking it as leave. Ned told him that Jim was fine, not answering the bosses question.

Then on Monday, when he came in, Jim looked like he'd got conjunctivitis. I had never seen anyone with redder eyes. I told him he should go to the doctors, then when he started complaining about them stinging and not being able to stare at his screen for long, I sent him home.

Then because Ned wasn't around, we then decided not to tell Ned until he noticed he was missing. Ned asked about Jim as soon as he walked back into the office, so we had to tell him.
