Workers at the Asda supermarket chain have won the first battle in a legal fight for equal pay.
An employment tribunal has ruled that some 7,800 workers can now bring a case against the employer.
Asda had tried to argue that because workers were employed in different places their pay wasn’t comparable.
The workers bringing the claim are employed in Asda’s stores and claim they are paid £1 to £3 an hour less than workers in distribution centres.
The workers bringing the claim are mainly women and the claim could have far-reaching implications for the rest of the 180,000 people who work for the firm in Britain.
It could also have implications for pay claims beyond Asda.
A group of 400 workers at Sainsbury’s supermarket have a similar case.
A group of 17 workers is taking legal action against supermarket chain Tesco.
They claim a recent across the board pay rise disguised a decrease in pay for unsocial hours from double time to time and a half.
Workers say the decrease represents a net pay cut for people employed on an hourly wage.
It is a similar claim to one being made by workers at Marks and Spencer.
