I haven't been to work in a week.
Were you sick?
Yes, but I was able to accomplish many things at home.
That's great you accomplished a lot of stuff off work. Just make sure you don't take time off when you don't really need to.
Yes, I do it many times. I accomplish more when I'm not at work.
It's wrong to avoid going into work if others are expecting you there, but in today's climate, you may be able to work something out.  If your bosses also agree that you are more productive at home, you could work out a flexible arrangement.  Bring up the idea when you are back at the office.
