I'm pretty happy with this as well. I work 7-3, but I work those hours every day. I've walked out of meetings that have gone past 3 and no one has complained. It's been a great experience
Same here. What I did was creating an out-of-office calendar event for every day which basically blocks others from inviting me to late meetings. I stick very tightly to my schedule usually just +/- 5 minutes.
