How to see YTD Hours worked
The Current Earnings Report shows the hours.
Payroll → Reports → Paycycle → Current Earnings
You can choose multiple payrolls and the Hours Column will give a sum total of all hours for each employee. To select several payrolls (or all for the year), click the first payroll you want to include and drag the cursor through to the last. Or, hold the CTRL key and click each individual Payroll you want to include.
