Amazon.com Inc. is eliminating monthly bonuses and stock awards for warehouse workers and other hourly employees after the company pledged this week to raise pay to at least $15 an hour.

Warehouse workers for the e-commerce giant in the U.S. were eligible in the past for monthly bonuses that could total hundreds of dollars per month as well as stock awards, said two people familiar with Amazon's pay policies. The company informed those employees Wednesday that it's eliminating both of those compensation categories to help pay for the raises, the people said.

Amazon received plaudits when it announced Monday that the company would raise its minimum pay. The pay increase warded off criticism from politicians and activists, and put the company in a good position to recruit temporary workers for the important holiday shopping season.
