COVID-19 has brought parts of the economy to a standstill.
At a stroke, lockdown measures emptied the streets, closed shops, offices, pubs and restaurants, and consigned millions of people to the novelty of working from home, or the uncertainty of a furloughed salary.
Now, with the first indications that restrictions may be eased, businesses are wondering how they can reopen safely and, for all the government support on offer, whether they can survive – or if it is even worth trying.
Safely lifting the lockdown poses a profound challenge to business. At its heart is the new reality of social distancing – the requirement to keep a 2m (6.5ft) gap between staff, customers and colleagues to avoid the risk of coronavirus spreading.
It is the metric that may soon define the pace and success of Britain's economic recovery, and the culture and practice of workspaces for months and perhaps years to come.
Firms will have to cut attendance accordingly, retaining a work-from-home culture or thinning staff, and public transport will have to adjust accordingly. Sky News understands that FTSE 100 companies are already preparing for such measures to be in place until the summer of 2021.
The more immediate and damaging impact will be on customer-facing businesses such as shops, personal services and hospitality.

In pubs, restaurants and entertainment, it could mean a 50% drop in trade.
Bloomsbury Bowling in central London opened 15 years ago, in the same week the 7/7 bombers destroyed a bus in Tavistock Square just round the corner.
Owner Jon Dalton, who also runs a chain of pubs in the capital, has never suffered a blow to business like this.
"We went from 100mph to nothing. We had our best-ever year, and now we have no business," he told Sky News, speaking in a venue that typically hosted several hundred people a night.
He has furloughed more than 200 staff across his companies and is thinking about how he might return to some kind of safe trading.
For his pubs, he is working on an app that would allow people to order drinks remotely and have them delivered to avoid a packed bar.
In the bowling alley, he can close every other lane to ensure a safe distance, or split a single group of eight players across two lanes.
But both options would lead to a drastic reduction in the number of people he can accommodate and the revenue he will generate.
"You are looking at a 50% drop in revenues at best. Nobody knows how fast confidence will return, how soon people are going to want to go out," Mr Dalton said.

Like many in the hospitality industry, he wants the government to extend the furlough scheme beyond the current end date of June and, when the time comes to open, to scrap VAT for the sector so businesses can survive and perhaps tempt customers.
Pied a Terre, a Michelin-starred restaurant in Fitzrovia, offers a more sedate atmosphere but faces the same challenge.
David Moore opened the doors 28 years ago, only previously closing when fire ravaged the building.
Social distancing may be impossible for five members of staff in the narrow corridor that links the two dining rooms – and he will have to remove several of the 14 tables, taking revenue with them.
Mr Moore has used the furlough scheme to retain staff, but believes the hospitality industry needs a government-backed deal with landlords to survive a lengthy shutdown. The proposal is for nine months' rent to be deferred and tacked on to the end of leases, with a hardship fund for landlords who are as desperate for the income as restaurateurs.
Even if all that happens, he is unclear whether the numbers will stack up.
"It really is a small restaurant, but it can have maybe 40 people on the ground floor. Okay, I have got the rates holiday, for which we are really grateful, but if we're only going to be doing 20 people and I'm paying the same rent, it's going to be tricky to see how the business will make money, how it will survive," he said.
"If you gave me a favoured date to come back, I'd say let's do the first week of September, because that's historically busy for the hospitality world. But if we go that far, there'll be so many businesses that won't be able to survive due to rental payments, and other costs that just keep ticking along regardless."
Customers have adapted to social distancing in supermarkets out of necessity. Now the 2m gap and one-way shopping mark the way forward for high streets that are currently deserted.
