Let's work from home when the kids are sick, thank you great company that I am allowed to slave away for you while taking care of my sick kid! It isn't even a US company it seems.
Edit: guess I should have posted to unpopularopinions instead!
I just wanted to add I cut off the photo of the person on purpose. She is posting that with her sick child in her lap and that photo has been taken by some other person, not a selfie. If you are not feeling that the content of the post is bad, you hopefully still agree that presenting your sick child in an almost professionally looking photo to the world for LinkedIn clout is not great.
Just to comment on your first point, while in Utopia it wouldn't be worth mentioning, the fact that not every companys job listing even includes home office, that makes it not just worth mentioning, but means it needs to be highlighted. People look for jobs that allow some or full time home office (for whatever reasons, or in general). How are they supposed to find them if it's not mentioned anywhere?
