My stepdaughter is doing online learning this semester, and as part of the agreement to use that option, it was heavily emphasized that she would be expected to attend on time, just as if she were in regular school, and that it wasn't an option that should be chosen if there wasn't reliable internet availability. Part of what kids learn by going to school is how to stay on schedule. This strikes me as sane and reasonable.
Not a fan of calling the cops specifically as if the parent is working they really can't do much but I do agree, online classes should be as close to IRL classes as possible, not any of that bs teacher unions are demanding with assigning worksheets. Students should have schedules.
