“Trainer” is to “trainee” as “mentor” is to what?

My employer has instituted a formal mentoring program for new employees. I was horrified (but should not have been surprised) to read the company information that referred to the new employees as "mentees" in the mentoring relationship. Apparently the word has been in use since the 1960's (I don't know where it was first used). Is this word really considered correct English?
