I have union employees who get paid a wage differential when working on a project that crosses over into another local union. Has anyone had any experience with this? We are looking for a way to have 2 line items when entering time - one line item for their normal local wage and then another line item with the wage differential. This is posing a problem because if we record hours on each line item, then it does not correctly report the number of hours worked on that specific job. If we don't put the hours and just put a flat rate based on calculation then if we were to be audited, we wouldn't have payroll records showing what that was for exactly.
