With this investment, Amazon expects the contracted delivery workers in the U.S. to earn $20.50 per hour on average or more.

Amazon uses external operators via their delivery service partner (DSP) program to facilitate faster and more efficient parcel delivery. The DSP program, launched in 2018, consists of about 279,000 driving jobs and helps Amazon deliver 20 million packages every day across 19 countries.

The company said Tuesday that many DSPs already pay above $20.50 per hour and that the investment will help them provide better wages and benefits to drivers.
