Pay type "stat holiday pay" with the employees regular rate somehow changed to "stat pay - hourly premium" with the employees time and a half rate. How do I change this?

Hey there, donna151.

Welcome to the QuickBooks Community! At this time, there isn't a way to disable the stat pay hourly premium since this is mandatory. However, this article will help make sense of Stat pay - Average daily wage as well as Stat pay - Hourly premium.

It is a complete mess up with this change.  You can see many posts on this and how dangerous it was for many companies that overpaid their staff and how it has created more work for the payroll admins and now does not properly manage insurable hours
