- Bring in the new rows first into the union
- Add a record ID in-case some new rows have same info (e.g. Bob)
- Set the end-dates by using start date of the newer record
- Set the current flag using a unique tool taking only most recent
- Then remove people who have left completely (latest = y; but end-date exists)
