I’ve said you aren’t being unreasonable because I don’t think it’s unreasonable to expect workers to have childcare in place or to do their job to an acceptable standard. I do think it’s trickier at the moment to separate out folk who are struggling because childcare isn’t available yet, those who see the opportunity to save money on chins are costs and those who are just too distracted at home for whatever reason.
My kids aftercare told us they were closing permanently the day the government here announced they could reopen, it took me two weeks to find an alternative place for them during which time I had no after school childcare. I discussed with my manager how I’d deal with it and we agreed a plan, I kept her up to date with how the search for childcare was going.
I think employers have had to be incredibly flexible this past year with some managing that more than others - my DHs employer has been very difficult but even so my DH has been able to pick up his share of childcare etc. It’s been tricky though and I think it will be for a while yet.
I wonder if having a conversation with staff who have children - maybe as part of a regular 1:1 - exploring how home working is going, any pinch points, your own expectations might be more reasonable than a blanket ban.
You’ve also been dealing with this for a year, so lots of time to properly look at your homeworking policy which could probably do with a review in the current circumstances.
In saying that I think if they would have childcare in place if they were in the office, they should have it in place while working from home, which means you don’t need to specify an age because parents will make their own decisions based on how comfortable they would feel having their kids home alone after school.
