I think all the training managers should be forced to work 3 nights in row between the hours of 2300 and 0700 each and every month. Just think of how productive they could be without all the usual distractions!
What is bad for the trainee is worse for the instructor. The guy we had last go was destroyed by day 2 and he cared as much as we did. I know they volunteer for the job but they are much more exposed than the average line guy.
