Her commute is not the employer's problem.
We had quite a few people on home-based contracts before covid - this means if they attend the office, they claim travel expenses (although currently you need to get such travel approved by someone high up as a money-saving thing.) Some people were already on contracts with adjusted hours allowing them to work round school pick-ups and things like that.
Most of us were on normal 40 hours a week, 8- 17:30 contracts, but in practice, had a lot of flexibility (I usually worked from home once a week; starting/finishing times often varied, which HR encouraged because it meant we're not all sitting in traffic queues at the same time, so improves our green credentials, and departments as a whole are available for longer.)
Since covid, those of us on office-based contracts have changed to hybrid contracts, which means we are expected to ne in at least one day a week (some departments are teo or three days a week.) If you don't want to do that, you are meant to renegotiate your contract to a home-based one. In practice, I don't think many have, they're just not coming in. However, we are a department which is spread across about 7 or 8 offices in 5 countries, so we are almost never in the same place at the same time, and have been accustomed to using video conferencing since the technology has been available for it. (Other departments are different, especially legal and financial, which tend to be in-country; I'm tech.)
There's been guidance that office days should focus on face-to-face meetings and collaboration - if you're just going to spend the day on the phone, you might as well be at home.
But ot all comes down to the business and what they want. If someone can show the benefit to the business of being on a home-based contract, then put in a request for that, but the cost (time or money) of an individual's commute isn't something they'll be interested in.
