A split shift looks free on a schedule: two short blocks, same person. In some places (California and New York State, for example) it costs one extra hour at the minimum wage, and a day stretched over more than ten clock hours can owe the same premium. shift-roster-builder already flagged split shifts but gave no dollar figure.
Enter your local minimum wage on the page and the notice now adds up one premium hour per person-day that has a gap over an hour or a span over ten hours, burden included, and names who and when. The library function splitShiftPay also takes your own gap, span and hour counts and a California-style credit for pay above minimum.
It is an estimate for planning, not the search's objective and not a statement of any state's rule; check yours. It is tested on hand-built weeks, not on a real restaurant's payroll.
