Hire Date and Term Date Changes

Content

I'm looking for a solid process or analysis for when we have Hire Date or Term Date Changes.

Example 1: Joe was entered with a hire date of 3/15/21, but for some (usually random) reason or another it has been changed to next week, 3/22/21.  (we would change the termination date of the pending worker, and the hire date of the employee)

Example 2: Jane's termination was entered effective 3/15/21, but it needs corrected to 3/16/21  (we would correct the termination date on the work relationship page)

We have several teams that we need to notify when such changes/corrections occur noting both the before and after values.  I have not found a successful way to write an analysis to reflect this.  Does anyone have a solid process or analysis they could share?
