Amazon will pay all of its U.S. employees a minimum of $15 an hour, more than double the federal minimum wage of $7.25. The retail giant, run by the world's richest man, was criticized earlier this year after revealing its workers' median pay was $28,446.

Amazon says the new rate will go into effect on Nov. 1, covering all of its full-time, part-time, temporary and seasonal employees in the U.S.
