Yes, I also work fulltime and have T in the middle of the day. At first my co-workers thought I was taking a yoga class before lunch every Monday. Now I think most of them have figured out I see a T at that time. I've had to explain to my boss a few times why I can't attent some work event if it's at the same time.

I find that I really don't get much real work done on T day because my mind is not on work at all.
