There are certainly vacancies for full-time instructors at the moment but could you live on an instructor's pay? I tried working full-time as an instructor some years ago but could not survive on the pay. Like many instructors I was only paid for the time the engine was running and not for briefings, refuelling etc. I managed to go back to my previous employers and they let me go back on job-sharing, That way I could instruct and afford to live reasonably well. It would be different if you could find a PPL school that would pay you a salary but there are not many of those around.
