The leading business figures pledging their support include Dame Carolyn Fairbairn, director general of the CBI, Martha Lane Fox, and Dame Helena Morrissey.
The ‘Together’ coalition, which is behind the weekend’s events, aims to bring people together and bridge divides, to help build a kinder, closer and more connected society.
The Aviva Foundation has contributed £500,000 to 'Together', making it one of the three main financial contributors. The Aviva Foundation was set up in the UK to make good use of unclaimed assets of shareholders, providing grants to charities and social enterprises, that deliver social impact and create new opportunities, ideas and insights.
Ms Darlington said: “The weekend of the NHS’ anniversary will be an important moment for the nation.
"It will be an occasion to remember those we’ve lost during the crisis, to thank the NHS staff, key workers and everyone else who has helped us through, and to toast each other from our doorsteps, making the commitment to carry on looking after each other, and getting through the next few months and years together.
“We will not just be saying a huge thank you to NHS workers, but to everyone who has helped; our colleagues, our suppliers, our customers, and the millions of unsung heroes who have looked out for their neighbours or supported their communities.
“The outbreak of coronavirus has brought financial hardship and the loss of loved ones to many. We hope that our contribution to the /together campaign will go some way towards building more resilient communities in the UK.”
During the pandemic, Aviva donated all of its hand sanitisers, rubber gloves, antiseptic wipes and face masks to care homes, hospitals and social care staff from its York offices. With more than 1,000 items going to City of York Adult Social Care unit and North Yorkshire Police. Aviva employees have also been using volunteering hours to help their communities across Yorkshire.
On Saturday July 4, Aviva is asking people to join a moment of national remembrance by putting a flameless light intheir windows to remember the lives lost during the crisis.
Sunday July 5 will culminate in a big national round of applause at 5pm – the biggest clap yet – followed by a socially distanced moment where you can raise a glass or a cuppa with your friends and neighbours.
Aviva said the NHS itself will be saying its own big thank you to everybody who has helped it continue doing its job in the face of the biggest health challenge it has ever faced.
