To clarify the above. The "default report" cannot be filtered. These are just settings to control the default columns and sort. But yes, as stated above, you can make any report you like to be used for the Table Home page report.
But I also suggest that you make a button or link in your Dashboard to a list all report or a report of inactive employees, so users can easily find them. Users tend to treat the filter box on top of the table home page's report as a search box and get confused when they get no hits when looking for an inactive employee.
