Supermarket giant Tesco has announced 4,500 job losses.
The latest round of redundancies will affect staff at 153 Tesco Metro stores across the UK.
The Metro stores are the ones that are sized between the superstores and the Express stores, and are mainly located in city centres on high streets and near railway stations.
A statement from Tesco said: "These changes will allow us to serve shoppers better and to run our business more sustainably, in an increasingly competitive and challenging retail environment.
"Importantly, they will also allow us to better align the way we run our stores to the way that customers are shopping in them.
"The changes in our Metro stores will be focused on better tailoring them to how our customers shop. The Metro format was originally designed for larger, weekly shops, but today nearly 70% of customers use them as convenience stores, buying food for that day."
They added that there would be some "small changes" to 134 of their 1,750 Express stores.
Changes in these stores will include a slight reduction in opening hours during quieter trading periods at the start and end of the day, and simplifying stock routines.
The stores affected have not been identified.
Jason Tarry, UK & ROI CEO, said: "In a challenging, evolving retail environment, with increasing cost pressures, we have to continue to review the way we run our stores to ensure we reflect the way our customers are shopping and do so in the most efficient way.
"We do not take any decision which impacts colleagues lightly, but have to make sure we remain relevant for customers and operate a sustainable business now and in the future."
