It must be hard to get the balance of respecting your staff's professionalism and autonomy and still acting as a manager to ensure good service is provided to pupils/ students in general.
Some employees respond really well to being given full responsibility and autonomy to perform their roles with little intervention - they feel respected and it is an opportunity for them to really shine.
Unfortunately not all employees act like that, and the 'hands-off' approach for some just means their role is not adequately performed without someone overseeing what is achieved.
A manager may recognise these different styles in their workforce but would be liable to being accused of treating people differently if they took more time to manage some and gave defined expectations, but were 'hand-off' with those who demonstrated they were able to work autonomously and responsibly.
This is especially difficult for schools during lockdown, where there has to be flexibility and creativity in approach due to varying home circumstances for both staff and students - it's difficult to determine set expectations, and impossible to see what is actually happening when the working is done from home. Heads are depending on their staff's professionalism, and I think they are mostly getting it.
And leaders in education can make interesting decisions as well; in one of the places I work (not a school) the Principal told all staff at the beginning of lockdown that he only expected them to work a maximum of 3 hours per working day - and stressed that this was the absolute maximum!
Now this, on the face of it, was a lovely thing to do for staff; it acknowledged the external pressures many were under and the difficult home circumstances that might exist for some. But in all the weeks that have passed he has never redefined expectations, so some staff are still working to this - and it is our students that are being failed because of less contact time. I wouldn't be surprised if many of his colleagues on the management team were unhappy with this approach.
