Hey Jimmy, I'm glad you're having a good time there. If an employer is sometimes slow to notify his teachers about roster changes, that can be annoying, but of course it's not a major issue.
Assuming you can get to the end of your contract without having been cheated out of money earned, the final hurdle will be if you can get the various monies owed to you for your last month of teaching plus air fare reimbursement etcetera. Anyway, so far so good.
