I am looking for some statistics. We pay overtime based on all hours paid (not hours worked) over 40 for the week. Therefore, if an employee works Monday - Thursday and has a vacation day (or holiday, sick day, bereavement etc.) on Friday and then works Saturday, we will pay 8 hours as overtime. We have been paying this way for 30+ years.
I know that most companies do not pay this way. We are considering a change, however, I need to provide statistical data that will indicate the percentage of companies that use 'worked hours' instead of 'paid hours' for determining overtime. Is there any such data available? I have not been able to find any.
