Ours are not formally stated but are generally accepted to be 10-12 and 2-4. There is a consultation on changing them as part of a review of everything like this post covid.
I quite want a change as I would like to fetch my kids now and then if I am free, but can't think of a reasonable alternative to propose - is 10-2 a common set up?
Or should I ask for them to be removed completely? I feel that the business might not support that as they don't want people working out of normal hours in the main.
