Here is the solution:
<cfloop array="#employees#" index="i">
<tr>
<td>#i.getEmp_ID()#</td>
<td>#i.getFirstName()#</td>
<td>#i.getLastName()#</td>
<td>#i.getSalary()#</td>
<td>#i.getDepartment().getDEPT_NAME()#</td>
<td>
<cfloop array="#i.getPhoneNumbers()#" index="j">
(#j.getareaCode()#) #j.getphoneNumber()#
</cfloop>
</td>
<td>
<cfloop array="#i.getLanguages()#" index="k">
<li>#k.getname()#
</cfloop>
</td>
</tr>
</cfloop>
