Hi closecontour,
Within the payroll system for Leave Accrual to begin calculating for employees they must be included in a finalised PayRun. I would encourage you using a Employee Payment History Report found under the Reports tab, within the Payroll System.
This way you can filter the report from today's date back to the employee's start date to check if they have been included in any Pay Runs which will also show you the Date Paid.
If still unsure you are welcome to give our friendly support team a call who can assist with further troubleshooting by clicking here.
Thanks,
-Steven
