Many companies have held off from cutting jobs during the lockdown as a result of the scheme, under which the government pays up to 80% of the salaries of workers retained, up to 2,500 pounds ($3,150) a month.
Treasury chief Rishi Sunak has said that from August, firms will have to start making contributions to the salaries of workers that are retained but not working, and that the scheme will close two months later.
That's raised concerns that Britain will see a spike in unemployment then. In total, 8.9 million jobs have been furloughed under the scheme by 1.1 million employers at a cost to the government of 19.6 billion pounds ($25 billion).
