I was lucky when I entered the workforce. I ended up working at a dealership that the owner had been a mechanic in a Chrysler dealership in the 40s and 50s. In those days, he said, no one would help anyone. Everyone was on their own and it was kind of a toxic environment to work in, as in all knowledge was treated like a trade secret and if you were having trouble with something, or trying to learn, good. You would likely be long enough that maybe the next job would be doled out to the older more experienced guy that wouldn't help or offer advice. Anyway, the dealership I worked at was set up in such a way that helping others was encouraged, and for the most part, if the shop produced we all did well and the environment was friendly. When I opened my own shop I operated it in a similar fashion. That sort of environment breeds better work ethics, productivity and workmanship.
