Online retailing giant Amazon is raising pay for hundreds of thousands of workers in the US and the UK.
Amazon's lowest paid US workers will receive $15 an hour. In the UK, pay will rise from £8.20 an hour in London to £10.50, while outside London the rate rises from £8 an hour to £9.50.
The move comes after criticism of its employment practices, with complaints over its warehouse working conditions.
Amazon has also been attacked by campaigners for how much tax it pays.
The company is one of the biggest companies in the world, worth about $1 trillion.
Its founder, Jeff Bezos, is the world's richest man, with a fortune estimated at some $150bn.
'It's a start'
The new pay rates start on 1 November, and will apply to all staff, full and part-time, as well as temporary and seasonal workers.
The move will benefit 250,000 workers in the US, 17,000 in the UK and tens of thousands of seasonal workers.
Tim Roache, the general secretary of the UK's GMB union, welcomed the announcement but said more needed to be done: "Given their owner is the richest man in the world you'd think he could see fit to dig a little deeper, but it's a start.
Mr Roache said that 90% of the GMB Amazon members had said they experienced "constant pain at work".
The union said Amazon did not allow it to operate under its roof.
TUC general secretary, Frances O'Grady, said: "If Amazon is really serious about looking after its workforce it must recognise trade unions.
"Today's announcement is... only a start and shouldn't be spun as a huge act of generosity."
Amazon's move comes after widespread strikes by workers across Europe.
This summer, workers took action to coincide with the internet retail giant's Prime promotion event. Staff at warehouses in Germany Spain and Poland were trying to force the firm to offer better working conditions.
Political move
In the US, Amazon is also facing pressure from workers.
The increase in Amazon workers' wages coincides with a cross-US movement by retail unions to raise wages to a minimum of $15 an hour, the so-called "Fight for Fifteen" movement.
Already rival retailers such as Target and Walmart have had to raise their wages.
Major US companies are finding recruitment a growing challenge with US unemployment so low and are having to raise wages to attract staff.
The Democrat Senator and prominent Amazon critic, Bernie Sanders, told Reuters it was a good move that others should emulate: "I want to give credit where credit is due. There is no reason why other profitable corporations in the fast food industry, the airlines and retail should not be following."
Neil Saunders, managing director of GlobalData Retail, said politics had played a part in Amazon's decision: "The narrative that Amazon is an ungenerous employer at a time when the company's sales, profits, and valuation are soaring does not play well among many customer segments."
