Is it possible to get WFH in articleship?

I wanted to ask whether it is possible to pursue articleship with a WFH arrangement. Due to some personal problems, I might most possibly be unable to attend WFO regularly, which makes a remote setup much more suitable for me.

I understand that opting for WFH might mean missing out on certain learning opportunities and exposure that come with working from an office environment. However given my situation, I am willing to accept those trade-offs, so I'd prefer to get WFH even if it requires me to work overtime, but I'll be having problem to do WFO even if it doesn't require overtime.

I would like to know —

1. Do firms (whether small or large) offer WFH options for articleship?
2. Is it possible to negotiate such an arrangement with the principal?
3. How open are firms generally to accommodating such requests?

I would really appreciate some guidance on whether this is a possible option and what's the percentage of possibility?
