Actually, it's not a bad idea to just look for a new posting this year, if your P doesn't appreciate u. I reckon 7 years is long enough into a role that u can try something new for your own growth. As someone who is in my 4th posting after 15 years (including a 2-year HQ stint), I must say that with each new posting, I've learnt new things and become a better officer. Can try teaching at another school profile (e.g. go to primary sch if u're a sec teacher), go for secondment to an independent sch, or even try a HQ posting.
