Hi angel08,
Thanks for checking in. An unexpected change to an hourly rate would definitely be concerning.
The first thing to do is check the employee’s Standard Pay and Pay History details to confirm which rate is showing now and whether anything may have changed before the pay was processed. You can also have a look at this link for more info on how that works. To fix the overpayment, the steps will depend on whether the employee has already been paid. You can follow the steps in this link, which covers what to do in each situation.
Cheers,
Princess
