Care workers can un-assign themselves from scheduled Visits as long as they have the correct permissions. Administrators can control this permission using the Un-Assign my visit ACL in Settings>Roles & Permissions> Field Portal Roles>Scheduling.
To un-assign yourself from a Visit on the web app, log in to AlayaCare and go to Schedule & Work>My Schedule.
Click on the Visit you would like to remove yourself from and select More Details.
Enter any comments you would like to include and then click Save.
This Visit will be removed from your calendar and will appear in the Vacant Visits for the office to offer or re-assign.
