The only advantage to having the week where you’re scheduled to do a detailed (and prep-labor-intensive) monthly review with your boss be the same week as corporate budget prep is going on is that there is a definite chance that the review will get postponed. As it was today.
Net-net, no savings in effort (perhaps some increase) but it makes my schedule (work and otherwise) so much better. Assuming the gap isn’t backfilled with more work for me.
