Just as a not, I've had FedEx deliveries come through after 9PM in the last month. The on-time guarantee is suspended but I'm still impressed with how hard they've been trying (at least in my area).
Speaking with the FedEx folks in my area, they’ve been working 7 on, 1 off. At UPS we’ve been doing 6 on, 1 off as we don’t work Sundays per the union contract.
