If you are looking for exact words in the cells then try
=SUM(COUNTIF(F14:F43,{"OFF","Admin","Off site"})

OR incase you are looking for text string within the entries then try the
below..You can ignore Off site since "Off" is already mentioned in the search
list

=SUM(COUNTIF(F14:F43,"*" & {"OFF","Admin"} & "*"))
