Some things don't change, a few bitter individuals blaming the management for all the ills of the world. In my experience they were no better and no worse than any other bunch of management faced with some pretty entrenched working practices. Do change the record lads.
At the end the diamond was simply too expensive to run, with carriers flying off to competitors who pay their mechs peanuts and operate out of rickety sheds. Without a large tied customer (as enjoyed by operators own MROs) the market proved too volatile for an independent with high fixed property and labour costs.
Wishing luck to all the good ones left to find new jobs.
