Amazon.com Inc. raised the minimum starting pay for its workers at the UK operations to between 11 pounds ($13.50) and 12 pounds per hour.
Following a pay disagreement earlier this year, employees at an Amazon warehouse in Coventry, central England, went on strike for several days.
The company stated that the increase would differ by location and start in April.
“We’re listening to Amazon workers, and the message is very clear: this new pay rate is an insult,” said Amanda Gearing, senior organiser of GMB, the union representing more than 500 Amazon workers.
“So, in response, we will be consulting over the next few days and announcing a new wave of action.”
According to the union, the Amazon Coventry workers are asking for 15 pounds per hour to deal with a cost-of-living crisis that has caused strikes in various sectors in Britain over the past few months.
Last year, Amazon increased starting pay by 50 pence, bringing it to a minimum of 10.50 and 11.45 pounds per hour.
The UK National Living Wage – a minimum wage rate which does not apply to apprentices or workers aged under 23 – is set to rise by 9.7% at the start of April to 10.42 pounds an hour. ($1 = 0.8151 pounds)
