Someone in our marketing department (who has access to duplicate merging but not employee files) somehow merged two "customers" together thinking they were duplicates -- however, one of the entities was actually an Employee record.  I'm not even sure how that can happen since Employee records are not eligible for duplicate merging -- and certainly not with a Customer record.

This has caused several huge problems -- including:

1) exposing transactions that are not normally visible at the customer level
2) marking the customer "inactive" causes the employee file to also go inactive whereby removing from payroll, etc.
3) removing login access from the customer also shuts off the employee access (which is even a bigger problem since the employee record is the Administrator of NS... luckily we had another Admin login to give access back to the employee record)
