Well, which was it? Was he taking his daughter to therapy or working from home? If his daughter requires additional care, he needs to care for his daughter, but that can't interfere with work. If your kids are not disabled, they may not be interfering with your work, and therefore, when you are working from home - you are, in fact, "working" from home.
Why is this person entitled to being paid to "work at home" when he's not actually "working" while at home, he's actually caring for his daughter?
People are confused. Working from home still means "working". It doesn't mean, be at home and do what I want but get paid, or not work as hard.
Maybe he thinks it should mean: I'll get the work done on my own time. But, if the work needs to be done that day, he still needs to be WORKING from home - and not doing something else.
