It's possibly the ultimate home office: dangling off a cliff-face over the Irish Sea. But for Jason Griffin, a 34-year-old call centre consultant from Glasgow, Scotland with a taste for adventure, it was the perfect spot to put remote-working technology to the test.

The pandemic-induced change to working habits in 2020 looks set to continue, and has given rise to the 'digital nomad': people using technology that allows them to work from wherever connectivity is possible.

Griffin works with Five9, whose call centre software is used by global clothing, education and sports brands amongst others. He said that as long as he has a mobile connection and his laptop, he has everything he needs to do his job as good as - if not better - than if he were in a busy office. And to prove the point he set up a temporary office perched on a portaledge on a cliff-face on the island of Anglesey, off the north coast of Wales.

"I will be working all day from that ledge and taking and making calls, interacting with internal staff while I sit there at this ledge on the side of a cliff, just showing that remote literally means remote," Griffin said.

Call centres are one sector where remote working and technology has kept companies connected to customers, albeit remotely. But the digital revolution has seen an ever-increasing trend for working remotely.

"What we're seeing is the rise of the digital nomad: people that do not want to be constrained in terms of where they work or where they live, for that matter," explained Ade McCormack, a digital strategist and author of "Beyond 9 to 5: Your career guide for the digital age".

He added: "The untethered workforce would appear to be the way forward... as the war for talent becomes increasingly acute, it will be the talent that determines the conditions of work and not the employer. So I see that's going to be one of the major post-industrial era shifts."

More employers in Britain say working from home is increasing the productivity of their staff, according to a survey published on April 1. A third of employers think the shift to home-working has boosted productivity, up from 28% last June, the Chartered Institute of Personnel and Development said.

It remains to be seen how permanent the shift to working from home proves to be.

A survey published in March by accountants KPMG showed most major global companies no longer planned to reduce their use of office space after the pandemic, though few expect business to return to normal this year.

Griffin, meanwhile, is planning his next extreme remote office experience this summer, likely to be an uninhabited island in the Outer Hebrides off the western coast of his native Scotland.
