Amazon, which has faced political and economic pressure to raise pay for thousands of employees, is boosting its minimum wage for all US workers to USD 15 per hour starting next month.
The wage hike will benefit more than 350,000 workers, which includes full-time, part-time, temporary and seasonal positions.
Employees at Whole Foods, which Amazon now owns, will get the same pay hike.
Amazon's hourly operations and customer service employees, some who already make USD 15 per hour, will also see a wage increase, the Seattle company said.
Amazon, with more than 575,000 employees globally, took it a step further Tuesday, saying that it would become an advocate for better pay everywhere.
A public policy team employed by Amazon will begin pushing for an increase in the US federal minimum wage of USD 7.25 per hour.
"We intend to advocate for a minimum wage increase that will have a profound impact on the lives of tens of millions of people and families across this country," Jay Carney, senior vice president of Amazon global corporate affairs, said in a statement.
Amazon has faced criticism from labour rights groups and others over pay and working conditions at its warehouses.
Ne of its harshest critics is US Senator Bernie Sanders.
His Twitter account, which has nearly 9 million followers, frequently points out the disparity between Amazon's median employee pay and the vast fortune of CEO Jeff Bezos.
Pay for workers at Amazon can vary by location. Starting pay is USD 10 an hour at a warehouse in Austin, Texas, and USD 13.50 an hour in Robbinsville, New Jersey.
The median pay for an Amazon employee last year was USD 28,446 worldwide, according to government filings, which includes full-time, part-time and temporary workers.
Amazon has revolutionised how people shop online and is the world's dominant internet retailer. In two decades the company expanded far beyond its bookseller beginnings, combining its world-spanning retail operation with less flashy but very profitable advertising and cloud computing businesses.
Last month it became the second publicly traded company to be worth USD 1 trillion, hot on the heels of Apple.
But it shares one potential hurdle that is growing higher for almost all employers: a tightening labor market.
The last hiring figures from the US Commerce Department showed that in August, the pace of hiring rose again and wages grew at their fastest pace in nine years.
Competition among companies for qualified workers is growing more intense, and they are increasingly willing to pay.
Last fall Target committed to giving its employees USD 15 per hour by the end of 2020. And in January Walmart raised its starting wages to USD 11 per hour.
But corporate profits in the US are booming, and that wealth isn't being spread out nearly fast enough for many.
On Tuesday, fast food workers in Michigan are going to kick off a series of protests in the Midwest and elsewhere around the country in support of unions and a USD 15 minimum age.
Neil Saunders, managing director of GlobalData Retail, said Tuesday that while Amazon's wage hike is a politically savvy move, it's also a change made out of economic necessity.
With a healthy US economy, Americans looking for work have an increasing number of job options, so Amazon has to find ways to entice people to join its company.
Amazon is also increasing wages in some areas outside the US The company announced that the minimum wage will be 10.50 pounds an hour in London and 9.50 pounds in other parts of the UK. The increases will include 17,000 Amazon employees as well as 20,000 seasonal workers.
