I was offered and accepted a position at a school I really like (ideal grade, subject, location). It's an established charter school with an excellent progress report from the DOE. I am truly thrilled. However, I'm wondering if I shouldn't go to two interviews I lined up before the offer. There are two reasons for this, both of which I know are mostly my own neuroses. First, it is an at-will agreement, which I've never worked under before; and, second, my family, who really look down on teaching, have me fearing that the position will disappear because of funding. Am I crazy to consider going on these interviews?
