I think you are wrong. Education and training are very important if you want to develop your business and work with truly competent professionals. As for the benefit, I advise you to learn more about ROI. This is a coefficient that can be calculated using a special formula and find out how profitable the investment in staff training was.

It can not be true. Perhaps one training session is simply not enough.

I spent a lot of money on training my company's employees, and now it seems to me that there is no result. The plans also included the development of the site, and it would be better if I spent money on it.
