What do current part time scientists say about RSSL?

“Now I can help those new coming into the industry, coach the apprentices and share my knowledge of the science behind things that they may not have covered. And because of my years in the industry, I have knowledge I can pass on to all grades. That’s what keeps it fresh for me”
