A third of the workforce at Edinburgh Airport is to be made redundant.
Some 250 workers from the 750 directly employed by the airport will lose their jobs, with the impact of the coronavirus pandemic on the aviation industry being blamed for the cuts.
All areas of the business are affected, including frontline staff, management and support workers.
Edinburgh Airport chief executive Gordon Dewar said it is a “bitterly sad day”, as he revealed the airport is losing £3.5 million a month despite government support schemes.
He said job losses are “unavoidable”, but claimed the situation has been made worse by “an ill-thought out and unworkable blanket quarantine policy”.
In the announcement on Friday, the airport said the redundancy process will begin immediately and it includes both compulsory and voluntary reductions.
Redundancy letters will be issued from Saturday notifying workers to leave on October 31.
Airport bosses said more than 90% of people who took part in a ballot consulting staff and unions on the proposals for redundancy terms supported them.
Mr Dewar said: “This is a bitterly sad day for the airport and for those colleagues who are losing their jobs through no fault of their own but due to the impact of this dreadful pandemic.
“We have worked with unions and staff over the past four months to protect as many jobs as possible, but unfortunately we have to confirm this regrettable news as the business prepares for whatever comes next.
“Last year we welcomed a record 14.7 million people through our doors. This year we will be lucky to see a third of that and next year won’t be anywhere near where we have previously estimated, so the business has to be the right size to be in a position to survive and recover when it can.
“The furlough scheme has undoubtedly helped us to retain jobs and we are grateful for the UK Government’s support, as well as that of the Scottish Government through things like rates relief.
“Despite this, we continued to burn around £3.5 million a month as passenger numbers dropped dramatically and airlines drastically scaled back operations.
“It will be a very long road to recovery, and we cannot successfully make that journey while we are set up as a 15 million passenger airport.
“Aviation was one of the industries to be hit first and unfortunately will be one of the last to fully recover, so job losses have been unavoidable.
“The situation has been exacerbated by the introduction of an ill-thought out and unworkable blanket quarantine policy which has massively impacted on passenger numbers.”
First Minister Nicola Sturgeon spoke about the loss of workers at the Scottish Government’s coronavirus briefing on Friday.
She said: “I deeply regret the need for the redundancies that have been announced at Edinburgh Aiport today and my thoughts are with the workforce there and my thoughts are with the management there.
“We will continue to seek to support the aviation and the wider aerospace sector as much as we can.
“One of the biggest risks that we face right now is the importation of this virus to the country from other parts of the world.
“Quarantine is the best way that we can devise at the moment to reduce the risks of people bringing the virus in and then allowing it to spread.”
