From the Shifts tab, click the options button.
Select Create shift.
Enter the shift details (employees, time location, position, etc) and be sure to tap the repeat field to choose an option.
Tap the bar at the top to bring up the repeat options, then choose the frequency.
Next, choose the days of the week on which the shift will occur.
Be sure to set an end date as well, unless you would like the shift to recur indefinitely.
Finally, be sure to Save the shift.
You will now see that there are identical shifts created that repeat on your shift calendar.
