It is very unusual for teachers to vote to strike ime.
I started teaching in 1996 and have never been involved in strike action in all that time. I actually don't teach now anyway, although I am still in schools, and the union I was in has not announced any ballot results as yet.
Like one r two other jobs I don't think elderly teachers ae ideally suited to the job. Teaching needs vibrant, energentic and ethusiastic teachers. With the best will in the world most 67 year olds are not going to find it is easy to keep up the pace.
And who will be complaining when it is their child being aught be a 68y teacher who is struggling to keep abreast of all the new changes or who hasn't quite got the energy to run around after ther precious children?
The teachers pensions are pretty good but they are no where near what many other publicservice pensions were like, such as the police pension. It was a perk of the job. It compensates for the fact that teachers pay is often lower than that of pther equally as qualified professional jobs, jobs thtat many teachers could have gone into instead.
But yes, parents won't like it. Their support will wane quickly.
Especially as there are still many people - including certain posters here on MN - who pretty much thing teachers have such an easy ride, only work 9-3, have masses of holidys, etc. Like I generally say - if it is so easy, go and do it!
