Position Pay Rate: To set a default hourly rate, go to the Positions tab and open the position you would like to edit. When you click on the position, the position editor will open and you will see a "Default Hourly Rate" box.
To add in a default hourly rate for your workers, just click in the coordinating grey box and type in the pay rate. Make sure you click save. Once you have set a default rate on a position, any workers qualified for that position will be set at that default rate.
