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. Your e-mail address is optional. All rights reserved.
