This document provides instructions on how to use an employee roster interface to assign shifts, shift groups, rotational plans, weekly-off plans, and holiday sets to employees. It describes the steps to create new shifts and shift groups, activate or deactivate existing shifts, and add shifts to shift groups. It then explains how to select employees, assign shifts and shift groups to them with effective dates, set up rotational shift plans, and define the time ranges for assigned shifts, weekly-off plans, and holiday sets. The goal is to allow administrators to define and manage employee schedules and time-off plans.
