I bought a book and learned the technology in about three days. I wonder if they ever got their training. Beats me, they're probably still hanging out hoping to get a raise once they get sent to training. I've seen many occasions where employees use lack of training as an excuse for poor performance. The employee complains that they perform badly because of lack of training.
Employer provides training, only to have the employee find something else to pin the blame on.
After a few cycles of this, it is hard to convince the employer that training is actually valuable. This is an example of everyone having to pay the price because of a few bad apples. Training is a two way street. If you want to convince your employer to send you to training, perhaps you should start by establishing how you will pay the company back. This is a public posting area.
