They paid their employees the same amount UPS does?
Also, how does UPS manage to make more money than FedEx even though UPS employees are in a union?
Did some Googling. UPS at the end of 2011 had over 398,000 employees worldwide. They had $54.1 Billion in gross revenue in Fiscal Year 2012 with $807 Million in net income.
FedEx has 290,000-300,000 employees worldwide in 2012 depending who you ask. They had $42.6 Billion gross revenue in Fiscal Year 2012 with $2.03 Billion in net income.
So UPS takes more in but due to it's higher employee costs has less than half the net profit. FedEx has about 75% the number of employees, most of whom make considerably less than UPS employees, but takes in less revenue and has higher operating costs due to flying a higher % of it's freight.
If FedEx Ground eventually takes business from UPS it might not take long for UPS to be in the red as it has less of a profit cushion than FedEx. UPS does gross more than FedEx overall but that's due to a much larger market for low cost shipping as opposed to high cost overnight shipping. As FedEx Ground makes inroads with it's lower operating costs and Express shrinks FedEx profit should be substantially more than UPS. But doubtful that they'll share any of it with Express employees.
