Delete entries from Combo box without deleting historic data

[Guitarzan]

I'm using Access 2010. I have a form that has a combo box. The combo box lists all employee names and one has to be selected. I've been adding employees over time as new employees come. This DB is 3 years old so there are many employees showing in the combo box selection that are no longer here. I'd like to only have the current employees visible but I do not want to just delete them from the Table because then the historic data wouldn't be complete. How can I only show the current employees in the combo box and maintain the data in the table?



As an FYI, I'm pretty new to Access and have not used code at all.

Have another field in Employees table - maybe a date type to record date inactivated. Then filter combobox RowSource.
