Ours was Monday...the twilight crew (my only frame of reference) in my hub started at 5 pm....wrapped up at 1 am. Yesterday - started at 5, and was walking out of the building at 9:30 pm. Management that has been in the building for 10+ years said Monday was going to be the busiest / worst day of peak (and it was, by far)....but that it'll be smooth sailing from here on out. Interestingly, Cyber Monday and the Tuesday there-after were bad....and then things leveled out and ran just like they do during the non-peak season. I don't know how the day crews / delivery drivers in my building are fairing, but I know the night crew isn't suffering the "oh my god the world will end, we'll need 3 people per trailer" doom and gloom forecast we were repeatedly told about for weeks leading up to peak.
