If you haven't got the skills for the job why should anyone employ you? Or am I being too simplistic.
I can understand that if you are already in the employ of a company that introduces new technology the employee should be trained on this new technology at the employER's expense.
I accepted a promotion within a company for which I needed more training. I attended a training establishment at my own initial cost with the company reimbursing the fees AFTER I HAD PASSED the the examination each year. No pass no reimbursement.
After saying that I used to work for an airline that employed a pilot who didn't have a current licence! Obviously the pilot was able to get one... and he became a good friend.
