Etiquette: Do not try to poach someone else's governess for the next year before the start of term 4

It is just plan rude before that.  

This law was explained to me by a parent 12 years ago after she had watched me at our Term 2 minischool be unofficially interviewed without my consent.  As a governess you may be interested in that job but it feels disloyal to not be even halfway through your year before everyone knows exactly what you will be doing next year.
