From the developer: "Automatically schedule your employees to multiple daily shifts with Excel. The Shift Schedules S2-10-50 Excel spreadsheet automatically assigns up to 50 people to up to 10 shifts per day in response to your scheduling needs and your employee?s preferences and qualifications. The program automatically assigns days off and creates schedules from 1 week to 1 month in length. The spreadsheet produces individual and group schedules and comes in sizes for 6, 10 and 20 shifts for up to 500 employees. The companion S2-Shift Maker can convert your sales, or other time-dependant employee needs, into schedule shifts for a one week period. It also schedules employee breaks during periods of slack activities."
