Predictive-scheduling rules in cities such as Seattle, Chicago and New York usually ask for about 14 days of notice and attach a premium to changes inside that window. The window is counted shift by shift, so a change made ten days before Monday is late for the first four days of the week and early for the weekend.
We checked that with the shift roster builder's changes report on its built-in cafe. Each of five Wednesday call-outs was answered by rebuilding the whole week, priced at one hour of each moved person's wage with the caller exempt, and the change was dated 15, 10 and 3 days out.
The numbers. 15 days out: $0 in every case. 10 days out: $50 to $88. 3 days out: $68 to $174. One caller (Gus) cost the same at 10 and 3 days, because all of his moved shifts fall early in the week.
What to do. If a rebuild is unavoidable, do it early and read the list of moved shifts by day before publishing. The window, premium and exemptions here are typed in, not looked up: the tool does not know any city's actual rule, and the cafe is invented. The page has the table.
