“Most of which” or “most of whom”?
The following is a sentence from an email I recently sent, not knowing if it was the proper use of the word.
As I mentioned, I have two (2) clients in the OMAHA area for whom I have been moving freight for about 16 months.
My question is whether I should have used "for which" instead of "for whom".
I make every effort to use my native language properly, but I am often unsure of the proper use of some of these words.
