Plans have been announced for industrial action and protests by workers at online giant Amazon on Black Friday in more than 30 countries, including Britain.
Details were finalised at a summit in Manchester on Friday held by campaign group Progressive International.
Spokesman David Adler said Amazon's financial results showed that the company can afford to pay its workers a decent wage and negotiate with trade unions.
He said the global day of action on November 24 is set to be the largest yet, with workers going on strike and joining other protests.
The GMB union has announced that more than 1,000 of its members based at an Amazon site in Coventry are set to strike on November 7, 8 and 9 as well as Black Friday.
An Amazon spokesman said: "We always strive to be better, and while we know we've got more work to do, we're proud of the progress we've made.
"We've created millions of good jobs, while helping create and support hundreds of thousands of small businesses around the world.
"We offer great pay and benefits, and provide a modern and safe working environment which anyone is welcome to see by taking a tour of one of our buildings.
"We continue to invest in the countries and communities where we operate, and we're proud to be the world's largest corporate purchaser of renewable energy. That's part of our drive to be net-zero carbon by 2040, with billions already invested in packaging reduction, clean energy and electric vehicles."
