Planned hours
Go to: Roster → below the roster grid.
Planned hours charts what's on screen: hours per day (per week in Month view), published and not yet published, plus open shifts. It also shows each person's total against the weekly limit from Settings → Roster; people over it show in amber. Tap a bar for the numbers.
Example: Priya's chart shows Leo at 42 hours in amber against a 38-hour limit, so she moves his Friday shift to the open-shift row.
