Josh Kettler, the most fleeting chief of staff, said he had been “warmly welcomed” during his three-month stint.
The Duke and Duchess have always denied accusations of bullying.
They are nonetheless plagued by staffing stories, which have become as much a part of their brand as edible flower petals and appearances on US chat shows.
One source familiar with Team Sussex said there is “an undeniable pattern”. While supporters can make the case that this is ordinary staff churn, the trend is “clearly about the work environment”, they added.
Sussex sources speak of a “transition” for the bosses, as the Archewell Foundation becomes Archewell Philanthropies. The change will see it fall under a “fiscal sponsor” model, customarily used by small charities to allow an umbrella organisation to run the admin and distribute any funds.
One critic described the Sussexes’ ambitions to run a global foundation as “essentially shuttered”.
Several sources who have worked with the Duke and Duchess since the pair left the Royal family have described their work in America as akin to a small “start-up”.
“You build, you scale, you test things, you rebuild,” said one source. “You generate a level of success and then sometimes you review. Does the infrastructure still support what you want to achieve?”
‘Show up, do good’ mantra
The new set-up of Archewell Philanthropies will allow the Duke and Duchess to keep up their mantra of “show up, do good” with fewer admin costs, the source added.
So what now for the Duke and Duchess of Sussex?
There is another media court case for Prince Harry starting in January. It is a safe bet that he will be back in Britain for Invictus, which will hold a “one year to go” event before the 2027 games.
There will be overseas trips, very likely to Africa, where the Duke maintains patronages including the Halo Trust and African Parks, and perhaps Ukraine again.
There are no firm plans for a dramatic pivot to new charitable causes.
Both the Duke and Duchess want to work in the US as and when they feel that they are needed – as they did for the LA fire recovery, for example, or the Uvalde shootings – and with bereaved parents on social media harms.
