You'd find a way to make it work if you had to or wanted to.
What happened in lockdown to many, isn't what happens with HE. Few would expect to continue their current job that fitted around school hours, while providing quality HE, though it's possible for some. Home ed childminders exist, quite often bringing their own children with them.
Generally people I know take advantage of no longer having to be tied to school attendance to work differently as well as educate differently.
For us, I was stuck with lots of legal action early on, and dealing with a damaged Dc, so subbed out most work for weeks to get us stable. I'm self employed and moved how I did everything and shifted the emphasis of my business to create more flexibility and a more child friendly working environment.
I also took them working with me as we figured things out. Previously they'd accompanied me at times as a treat only for the more exiting end of things.
We developed a nice sleeper vehicle with everything needed to provide internet facilities and run computers, engaged sitters, and I drove while they slept.
TBH it was all very messy at first but we found our grooves. Unconventional but enjoyed by all.
We became less mobile in order to be in the right places to access much needed practical equipment as exams beckoned. For A levels they were expected to behave like the young adults they where, and generally choose to come with me and earn money when not studying
Disability's changed what industry I now work in. With DGc's I'm either WFH or they come to my creative work spaces, and we work alongside each other.
People sort out whatever works for them. Some examples:
Two teacher friends share a job and child share, and top up incomes by tutoring both school and H/E children.
A couple do shift patterns with time off, with a housekeeper filling in.
H/E Au pairs do well improve their MFL's and international swapsies are a thing.
Another LP works nights and her DD stays with us and others to give them both support.
One in a prime location, has converted their home and air B&B's the bottom half.
Several separated mums with 50/50 care, mainly work while Dc's are at Dads.
One LP of 4, WFH as an online school tutor. Another teaches piano and violin mainly from home, Another wfh at night here for a different time zone, and another is a carer looking after a severely disabled child who benefits from her children being around.
