FedEx, UPS Find Formula for Delivering Seven Days a Week: Discount Sunday Drivers - Market Screener Sundays will soon look a lot like weekdays at FedEx Corp. and United Parcel Service Inc., as delivery drivers fan out to neighborhoods to deliver online orders to doorsteps. But there will be a key difference: Drivers working that day will be paid at a much lower rate than those who drive during the week. FedEx and UPS, with some assistance from the U.S. Postal Service, will rely mostly on this lower-paid army of delivery drivers as the companies work to turn a profit. The bulk of deliveries will be residential, which are more costly than deliveries to businesses. Both companies recently disclosed the new seven-day-a-week schedule, which starts in January after the busy holiday season.
