DON'T DO IT ..DON'T EVEN THINK ABOUT IT....I'VE BEEN IN LINE MAINTENANCE FOR 22 YEARS AND HAVE WORKED MY WAY WITHOUT ANY COURSES OR HELP UP TO FULL B1 LEVEL WHICH TOOK ME MANY YEARS OF BLOOD SWEAT AND TEARS OF STUDY. THE RESPONSIBILITY I HAVE IS HUGE AND THE WORKING CONDITIONS I HAVE TO PUT UP WITH ARE SIMPLY NOT REFLECTED IN THE PAY I RECEIVE.EG MY WIFE STARTED WORK PART TIME IN AN OFFICE,ONE YEAR AGO (NO QUALIFICATIONS REQUIRED FOR THE JOB) AND NO GREAT RESPONSIBILITY AND RECEIVES TWO THIRDS OF MY HOURLY RATE AND GREATER RESPECT AND PRESTIGE.
