The San Dieguito Union High School Board voted last week to reopen schools starting in January, despite warnings from district administrators, the teachers union and others that there won’t be enough staff and that the reopening violates state rules. The board voted 3-2 late Tuesday night to offer all students one-day-a-week, in-person instruction starting Jan. 4, and five-days-a-week in-person instruction starting Jan. 27. The board voted at 11 p.m., after receiving hundreds of public comments from students, parents and teachers arguing for or against reopening next month. San Dieguito serves about 12,900 middle and high school students at 10 schools.

Some said it’s not fair that other schools in the San Diego area have been open for months.
