How is there a difference between having a school aged child loitering around the house whilst you try and work and having them traipse around a covid ward? Or a factory? Or a fire station? Do you really need to have that clarified?![/quote]
We don't know, however, that the SD does any of these things.
You asked whether it was reasonable that the SD take her children to work. I don't think it's any less reasonable than expecting the OP to have then with her whilst she's working (your assumption that she's fighting fires notwithstanding).
I know that I could not do my job with a school aged child loitering around the house. Nor should I be expected to, particularly if the child is not mine.
And, bluntly, I wouldn't be prepared to lose my job, which keeps a roof over our heads, to facilitate childcare for anyone else.
It would be different if the OP was sitting on her arse drinking gin all day (although, that would still be her prerogative) but in this situation, I fail to see why her SD's needs should trump hers
