Workers for online retailer Amazon are still not receiving the real living wage - despite a vow by the firm that it would consider introducing the rate.

The firm met with ministers 18 months ago and claimed it would look at paying employees £8.75 an hour, however reports suggest staff at depots in Fife and Inverclyde are still earning less.

According to the Sunday Mail, employees earn £8.35 after two years' service - 40p short of the living wage. It is unclear what the rate of pay is for employees with less than two years' service.

Scottish Labour leader Richard Leonard said: “Amazon have a terrible record on workers’ rights and fair pay and conditions – we need to see real progress on this, not more hollow promises.

“It’s been well over a year since the SNP Government claimed they were lobbying them on the living wage and nothing appears to have changed.

“The SNP Government should be doing everything they can to ensure fair labour conditions for the people who work for Amazon."

The Scottish Government said it was in "continued dialogue" with the US company to ensure pay rates "are in keeping with our ambition to see the real living wage replace the national minimum wage".

Amazon - owned by the world’s richest man Jeff Bezos - has faced fierce criticism over its working conditions, including claims staff were made to opt-out of the EU working time directive and sometimes slept in tents outside distribution centres over its busy Christmas period.

A spokesman for Amazon said: "The pay rate for permanent Amazon employees increases over their first two years of employment, when all employees earn £8.35 an hour and above.

"All permanent Amazon fulfilment centre employees are given stock grants, which over the last five years were on average equal to £1,000 or more per year per person.

"Employees are offered a comprehensive benefits package, including private medical insurance, life assurance, income protection, subsidised meals and an employee discount, which combined are worth more than £700 annually, as well as a company pension plan."
