How? The child is not a new born or sick. They just can't go to school.
I think they need to follow the spirit of the law on this rather than quibble over the details. It is a public health issue, they are being forced to stay home from school to prevent the spread of the virus.
It's just like the people in quarantine on the cruise ships. How many are out of vacation time and stand to lose the health coverage because they can't get back to work? Imagine losing your insurance, then getting sick because you were forced into close quarters with other people who are sick. Just one more reason to never go on a cruise.
Now, getting back to the preceding issue, that being families where both parents must work. I wonder what would happen if roughly 1/3 to 1/2 of the labor force removed themselves to stay home and raise their families. The value of labor would necessarily go up, right?
I guess we would lose the day care sector, and probably cut back on some teaching positions, but aside from that, the demand for labor would be high. Maybe the union should start encouraging single income households?
