If necessary, you can delete the relationship from the Relationships tab of the constituent. However, if an employee was promoted or changed jobs, rather than deleting the old item, you should edit the employment information to add an end date to old job or title, which makes that item inactive. You can then add a new employment history item for the new job or title. This gives you a more complete view of the constituent’s employment history over time.
To delete an item from the employment history, on the Relationship tab select the item from the Employment history list and click Delete. When you delete an item from the employment history, the relationship with that organization or individual is not also removed from the Relationships tab.
