A recent study from UK insurance company, Norwich Union, suggests that a quarter of transport accidents could be avoided through proper training.
While you may be thinking, "what does that have to do with me or my line of work?" I would caution you not to be cheeky and will tell you that it underscores the importance of training and proper education.
Even in this specific example where studies revealed that drivers would be better served by more training, which would likely result in fewer accidents, it shows that companies need to make sure that the employees are able to do their job to the best of their ability and are given the tools and education to do so.
In my own experience, it seems that companies are far too lax when it comes to continued training. One could reasonably argue that employees would be better served by continually learning how to do their job just a little bit better. In fact, some countries even require a company to earmark part of the budget for employee training.
Instead of viewing such budget as a drain, it should be viewed as an investment: in the company, in the employee, and in one's own bottom line. This is how new techniques are learned, not to mention tips on how to improve efficiency or productivity.
Think of this investment like auto maintenance. Your car requires really scheduled maintenance. Failure to upkeep the car can result in decreased performance, potential error, or just disappearing on you when you most need it.
