I've encountered a totally different school of thought on job security in the early 2000s after the fall of the dot com era. Many jobs were cut. "Outsourcing" became a dirty word. My good friend got a year-long internship in banking industry in early 2000s. When I asked him how the real world worked, he was taught to hoard as much knowledge as he possibly could and not share it. Sharing knowledge means someone could do his exact job. He had no desire to learn new skills. He worked with folks who had been with the organization for 20+ years and that's how the workplace worked. He and his colleagues were so afraid that their job would be outsourced. We are not friends anymore. I bet he still works for the same organization. He may not be wrong about hoarding the knowledge and working in a slower pace industry: Doing so could be an easy ticket to gain job security for life.
