Instructing is not just a vocation, it is a hugely responsible job, since we have the safety and care of our students in our hands.
It is desperately sad that the employers do not recognise this and reward it commensurately with commercial flying. An example of this is that aerial photography work or pleasure flying is paid at a higher rate than instruction, a fact that seems bizarre given the qualifications required for instructing. However, after ten years of instructing I still think it is the most rewarding job I have ever done, even though I could have earned ten times as much in the City.
If you are any good at instrucitng then you owe it to the Profession to stick it and carry on.Perhaps one day we will succeed in getting the true recognition that we deserve.
