It happens, your employee indicated they finished 30 minutes after their scheduled shift, and you don't agree ! No worries ! You can edit the shift when validating your employee's worked hours from the schedule and justify this change. Once the hours have been validated, your employee won't be able to make any further changes.
Head to your schedule :
Click on the shift you want to modify
Add the desired changes in the "actual hours" section (hours, break times, type or number of meals)
Add a comment to justify this change if you wish
Validate
What if you prefer for your employees not to be able to declare their worked hours ?
That's possible too ! This option can only be modified by admins and directors.
Head to Settings > Locations & Schedules > Your location > Scheduling :
Un check "Employees can declare their work times"
Save !
There you go !
