The supermarket giant is moving to a night-to-day replenishment model in 69 of its largest sheds, axing round-the-clock opening hours in eight of those stores.
Tesco is also bringing together different service desks including customer services, click-and-collect and tobacco and lottery points to allow shoppers to “get everything they need in one place”.
The grocer said it has launched a consultation with 3,000 staff who will be directly impacted by the changes.
But a spokeswoman said Tesco expects “the vast majority” of those workers to remain with the business.
The changes, which will be made gradually from the summer, come just over a year after Tesco ended 24-hour opening at 76 of its 400 supermarkets that operated around the clock.
The eight further stores that will switch to 6am until midnight opening hours “in the coming months” are:
- Galashiels Extra
- Holyhead Extra
- Ilkeston Extra
- Kilmarnock Extra
- Falkirk Grahams Road
- Edgware Road Metro
Tesco is one of a number of retailers who are making operational changes in stores as they seek more efficient ways of working.
In February, Tesco said it was axing 1,700 deputy manager roles in its convenience stores as part of a wider move to create 3,300 lower paid shift leader roles.
Grocery rival Waitrose put 180 store management level jobs at risk as part of a move to simplify the structure within its 350 stores, while stablemate John Lewis is axing almost 400 jobs amid “structural changes”.
The high street bellwether’s new boss Paula Nickolds has warned that more redundancies are likely this year.
Tesco’s UK and Ireland boss Matt Davies said: “We’re committed to improving the way we serve our customers and this week have discussed making further changes in a number of UK stores with our colleagues.
“These changes will help us run these stores more simply and deliver the best possible service for customers.
“We appreciate these changes will impact the roles of some of our colleagues and we will work with them to ensure they are fully supported throughout this period.”
