Tesco will no longer have deli counters in its stores as part of a shake-up of shop management roles which will impact around 2,100 jobs.
Britain's biggest supermarket said it is reducing the number of lead and team managers in large shops as part of an overhaul of its management structure, which will impact around 1,750 workers.
Tesco said it will also introduce around 1,800 new shift leader roles in stores, who will be in charge of operational duties on the shop floor.
It will close its remaining counters and hot delis at stores from February 26, having previously removed counters from the majority of shops.
Tesco said all affected workers will be offered alternative roles. It did not say how many staff work on counters and delis.
The retailer also said 350 workers will be impacted by a series of localised changes, such as the closure of eight pharmacies and reduced hours at some in-store post offices.
Jason Tarry, Tesco chief executive of the UK and the Republic of Ireland, said: "These are difficult decisions to make, but they are necessary to ensure we remain focused on delivering value for our customers wherever we can, as well as ensuring our store offer reflects what our customers value the most.
"Our priority is to support those colleagues impacted and help find alternative roles within our business from the vacancies and newly created roles we have available."
