When we started our careers we all had choices. We all weighed up the pros and cons of the public or private sectors.
So to say "I don't get it in the private sector, so why should you in the public sector" is unfair.
t' like hiring a buildre for, say, £1,000. Then, when he's done the work, saying "But I don't get £1,000. So why should you?"
Because he did the job asked of him under the agreed conditions.... That's why.
If you can't see that? Well, those lazy public sector teachers have let you down.....
