Shift Parent OS exists because Pitman schedules, 24/48 rotations, mandatory overtime, and night-shift recovery are not edge cases for the parents who work them. They are the whole schedule.
We assume you already know what your rotation means. Articles do not explain a Pitman week in the first paragraph — they get straight to the custody math.
Mandatory overtime, shift swaps, fatigue, and sleep debt are mentioned by name, not softened into "self-care." We talk about sleep, recovery, and scheduling as the concrete things they are.
