Two of the UK's biggest High Street retailers, John Lewis and Boots, have announced 5,300 job cuts.
Boots has said 4,000 jobs will go, while John Lewis is shutting down eight stores, putting 1,300 jobs at risk.
The moves come amid warnings that new economic support from Chancellor Rishi Sunak will not be enough to stop millions of workers losing their jobs.
Mr Sunak admitted that he would not be able to protect "every single job" as the UK enters a "severe recession".
Boots is consulting on plans to cut head office and store teams and shut 48 of its more than 600 Boots Opticians practices.
It has not yet said which outlets will close, but about 7% of its workforce will lose their jobs.
John Lewis said department stores in Birmingham and Watford will not reopen as the coronavirus lockdown eases. It also plans to shut down its At Home stores in Croydon, Newbury, Swindon and Tamworth and travel sites at Heathrow airport and London St Pancras.
Mr Sunak unveiled a series of measures on Wednesday aimed at saving jobs, including a one-off £1,000 payment to employers for every furloughed employee retained to the end of January 2021.
He also announced measures to benefit the hospitality sector, including giving diners 50% off eating out from Monday to Wednesday in August.
Culture Secretary Oliver Dowden said the moves to support restaurants, pubs and cafes could also help retail.
"We very much hope that when people go to their local pub or their restaurant to eat out, those are often in the centre of towns, hopefully that will encourage the footfall to those areas so we get more people going to our shops as well," Mr Dowden said, speaking after announcing the reopening of gyms, indoor pools and outdoor theatres.
