I can't speak to the DUI, but our hours are full or half-days only. I haven't done elementary in a while, but it used to be from 7:15 - 2:55. I recommend getting there about 20 minutes early to read over the lesson plan, gather an by supplies, and locate the teachers lounge.

Secondary is 8:10 - 3:30. I usually arrive about 15-20 minutes early because my kid wants time to hang out with her friends before class. Otherwise ten minutes would be sufficient because class doesn't start until 8:20. I usually spend those few minutes locating the nearest restroom, reading through the sub notes, and putting my lunch away. The kids leave at 3:25, so I clock out by 3:30 at the latest.
