Supermarket giant Asda has said that some staff are still waiting to receive their correct pay, days after an IT issue left thousands short in their pay packets.

Asda said some 9,500 colleagues may have been underpaid as a result of an IT glitch

The retailer said that two issues were behind the underpayments: one involving a miscalculation of overtime and premium rate shifts, and another arising from holiday pay errors, according to The Grocer.

An Asda spokesman told the publication: “We recently launched a new HR system and conducted pre-emptive checks to identify any potential issues before colleagues were paid this month. These checks found a potential problem with holiday pay that could have resulted in a pay discrepancy for some hourly-paid colleagues.

“We have taken immediate and proactive steps to correct this to help ensure there will be no shortfall in pay for these colleagues this month.”

Asda had written to store managers last week warning some 9,500 employees could be affected by the miscalculation of holiday pay.

Changes in the way staff are paid are the result of Asda’s move from its old Walmart legacy IT platform to a new purpose-built one.

The Grocer reported that some staff may have been underpaid by as much as £1,000 if they were affected by both holiday and overtime payment issues.

The retailer said that no staff member would be left out of pocket by the incident and that the majority of its 150,000-strong workforce had been correctly paid.
