i have been a teacher for nearly 8 years so i complained about the style of training to other training crew members....combined with stress, fatigue and other things, i was very edgy, and people say things under pressure. when all this happened, id been up at 3am in the morning, until 3 am the next day, and doing at least 15 hrs sleep monday-friday. the training was all completely theory based, which was an issue for me, because i learn in a practical way.
