How does an English teacher NOT speak English????

Just had a meeting with two of my three new co teachers. Ummmm....two of them do NOT speak a lick of Englishee. Not one lick. Heck, even some of my students speak better English. 
How da f@ck did they get selected to teach this class this school year? Did they draw the short end of the stick? I'm guessing so. UGH!!!!!!!!!!!!!!!!
