Do you work with me?
I've been fighting this battle for the last 3 months. They've added almost an hour of meetings every morning at 9am. Half the office shows up at 8:30. That's enough time before the meeting to check email and get coffee, so essentially no work starts until 10. At 10 they get back to their desks, there's a bit of whining about whatever management has changed that day and how stupid the meetings are, some email correspondence and by 11 nothing is done and they go to lunch. They get back by 11:30-12 and finally start doing work. So your 8 hour workday turns into maybe 4 hours of real labor time, and no one works 100% of that.
