If employees need to swap schedules, the easiest way to do this would be delete the schedules for each employee and re-add them with the correct shifts. If an employee needs to change their schedule to match another employee’s exactly, you can use the Copy Schedules button to overwrite their schedule for a particular date range with the other employee’s schedule.
Additional Information
The goal with scheduling is always to create a base template of a week (or more if you have a multi-week rotation), and then Mass Copy the schedule into the future. Once you’ve done the mass copy, you can make small adjustments as needed in the Employee Schedules screen.
