More than 1,600 Tesco jobs are at risk as the supermarket plans to axe overnight roles at a number of stores and close its discount arm Jack's.
Yesterday the retailer confirmed plans to close Jack's, with seven stores shutting for good and the remaining six becoming Tesco shops.
Today it announced it would cut jobs for thousands of its Tesco night staff too.
The combined changes will put around 1,600 workers at risk - 130 from Jack's.
A Tesco statement said it needed fewer night staff because it was now doing more shelf-stacking during daytime.
The supermarket said: "Following successful rollouts, we have shown that by moving our overnight stock replenishment to daytime trading hours, we can ensure more colleagues are available on the shop floor to help customers at peak times.
"We have therefore taken the decision to move our overnight stock replenishment into the daytime in 36 large stores and 49 convenience stores."
The supermarket will also cut overnight staff by swapping 36 of its petrol stations to only drivers to pay at the pump, not through a cashier.
The supermarket has around 3,000 jobs vacant, and will try to move the 1,600 affected staff into these if possible.
Tesco UK and Republic of Ireland chief executive Jason Tarry said: "We operate in a highly competitive and fast-paced market, and our customers are shopping differently, especially since the start of the pandemic.
"We are always looking at how we can run our business as simply and efficiently as possible, so that we can reinvest in the things that matter most to customers.
"The changes we are announcing today will help us do this.
"Our priority now is to support our impacted colleagues through these changes and, wherever possible, find them alternative roles within our business."
Jack's was launched in 2018 as part of the brand's centenary celebrations, promising to offer 'great-tasting food' which was grown, reared or made in Britain at the lowest possible prices.
It also stocked some familiar grocery brands and a range of general merchandise on a “When it’s Gone, It’s Gone” basis.
Earlier this week The Mirror reported that prices of the same items at a Tesco have increased by nearly 20% in the two years before the Covid-19 pandemic.
The cost of living is on the rise, largely due to the pandemic, and poverty campaigners have shared their concern about how this will impact families.
A list of Tesco goods which cost £70.61 in January 2020 costs £83.26 now- an approximate 18% rise.
The 50 items in the trolley would typically feed a family for a week, the Manchester Evening News says, and includes sausages, cereal and crisps.
Tesco was founded in 1919 in Hackney, in the East End of London.
