To add export functionality for the employee, you have to customize list_in/cr/chg.htmpl and add some search filters or just declare the filters section.
For example, in list_in.htmpl just add the next lines after "<PDM_INCLUDE FILE=std_body.htmpl>":
<SCRIPT LANGUAGE="JavaScript">
<PDM_MACRO name=sfStart create=false factory=cr>
<PDM_MACRO name=sfEnd>
</SCRIPT>
This will enable the filters and also show the Export button. You can also add some fileds for filters in this section.
