They probably excused you for the haunted house job because it was a short-term Halloween gig. Now you've replaced it with a job that will require a consistent absence from meetings, and they're letting you know that's not going to fly. I agree with Kevin -- sisters find sisters jobs at their places of employment all the time. Also, you don't owe 2 weeks notice to a job you just started; just tell them the schedule doesn't work with your previous obligations.
