First, the use of the word 'propaganda' is entirely inappropriate by the NUT (when describing Forces recruiting). Propaganda is used to further a cause or doctrine, such as Marxism or Nazism (for example), not recruiting.
Secondly, does the NUT practice what it preaches? Let's investigate...well, I'm sure you've all seen the recruiting adverts for teachers on the TV and in the press - the 'use your head; teach' ones. Do any of those adverts state that, if you become a teacher, that you may be subjected to assault by the pupils (physical or verbal); that drugs and weapons are prevalent in schools; that if you try to control your unruly pupils, that you will likely be charged yourself; and that there is a good chance that you will leave the profession within 3 years because of ill-health, stress or assault? Has the NUT done anything to make sure that these facts are properly represented? Errrr, no.
Thirdly, last week the Training & Development Agency for Schools (a govt dept that organises teacher training) sent out a letter to all teachers who have left in the past few years, encouraging them to come back; there is a staffing crisis in schools. The letter cites improvements in the job, such as more pay and better hours. One John Illingworth, who resigned as a head teacher 3 years ago due to mental illness bought on by stress, addressed the NUT Conference yesterday stating that the letter is 'damned lies; we shouldn't encourage people into teaching on the basis of lies because, if we do, half of them will leave in the first 3 years'.
NUT - get your own house in order first.
