I'm not belittling experience and yes of course, inform your employer....but why would anyone else need to know? What do you need to prove? Just get on with the job you've been employed to do.

These things don't automatically make you a good teacher. From what I've seen, the good experienced teachers just get on with it and do their job well. The bad ones tell you at all opportunities and then when things don't work out, blame the school....the students ....the water....anything, but rarely do they look at their own shortcomings.

I'm glad you have a sense of humour. No doubt you appreciate my exaggerations and cycling proficiency test joke.
