You will be paid for the time as entered and approved through ESS. If there is a mistake, you must notify your supervisor of the error. If the approver has not yet approved the timesheet and it is in a pending status in ESS, the supervisor can go in and make the changes. The supervisor would also need to document in the comments field that they spoke with you about the changes, and why the changes are being made.
The supervisor then notifies Payroll Services by email, and Payroll Services corrects your pay on the following paycheck. It is important for the payroll system to have accurate information so you are paid correctly. As we are tracking sick and vacation time in the ESS system, any adjustments to those hours also need to be submitted to Payroll Services so your accruals are correct.
