When you create shifts, you can leave the shift end time open-ended by checking off 'Close'.
If we use the example above, Tim will see that he works from 5pm-CL.
However, in order to get more approximate labor costs for closing shifts, you will want to enter your close times. To do this, hover over your profile picture > Locations/Departments/Roles > Locations.
Click on the Location you'd like to edit > Close times tab:
Once you click Save, all closing shifts will pull in your hours of operation in order to determine the approximate labor costs.
