I've been pretty lucky too....even though my boss hates me, I established my T schedule before he became my boss and I basically just said - BTW, this is my schedule.

One day a week, I skip lunch and leave an hour early to make it to group T.

Another day each week, I take a late, long lunch. I'm salaried, so it doesn't make a difference there. I do end up taking longer than necessary, because after my sessions, I find that I need a good half hour to collect my thoughts....and even then, I find that I am less productive when I get back to work. It's definitely difficult for me to get back into real life mode after a T session.
