On Combo, you can easily move an upcoming shift from one location or team to another.
If they are past or in progress, you will need to create them again from the right team.
Let's look at how to do this for future shifts ! First, make it possible to schedule your employee for the 2 shifts (the one where the shift was created, the one where the shift is to be transferred).
Head to your employee's profile > Work Time tab :
Click on "Edit" in the Scheduling section
Select the team for which your employee is to be scheduled
Head to your schedule for the concerned week :
Click on the shift
Scroll down to "Move this shift to another team"
Choose the team to transfer to and the label to assign
