I don't usually check the details of my monthly pay check from the school district much beyond the number of days worked to make sure it's correct.
So I was a bit surprised to notice an entry in a column that has historically been blank since I started working as a substitute teacher. The column labeled "Sick Leave Balance" was no longer blank! Evidently a new California law went into effect starting July/2015. My job classification now requires the school district to pay for sick days.
How it is calculated, that still a bit of a mystery but as far as I can tell it looks like 1day/month of the school year....maybe.
