If you can't make the time to spend a few days a quarter with your workmates in exchange for the most generous and fair remote working package then perhaps you're not a good fit for Airbnb. Which is totally fair. But they're not exactly taking the piss here. For many (many) people a week long retreat is a perk not a burden.
But if you have a family you actually like/love - then a full week away really is a non-starter. Especially if its Sunday night and Saturday morning travel. School plays and parent teacher conferences don't get planned based on the AirBNB week long retreat schedule.
And if you are in a dual income family with the stereotypical two kids - if both of you guys are in similar work situations - then on your "on" week - you're gonna be the one doing 2 school pickups and all after school driving.
I also did notice that there are plenty of parents who will blame their children for things they themselves don't want to do and not be honest about it. It's not the children that are at fault there though.
In the end, there are plenty of WFH jobs that don't need on-site time at all so you can pick and choose. It's a great market for an engineer to be in now.
