Reconciling Union Dues Based on Work Date for Reporting to Vouchers which are based on Check Date

I am just wondering what other union customers do who automatically voucher their union dues which are generated based on Check Date, but actual union reporting is based on Work Date so how do you reconcile the voucher to the dues?

If my payroll crosses months for example some work days are in November and some are in December and my check date is in December, then my Voucher will be generated with a December check date, but what I am reporting to Union is November work dates which does not include this amount.

Just wondering how others reconcile between the two? Do you develop a report? Not automatically voucher your union dues? Don't reconcile because eventually it is a wash?
