Simon Langlois studied government employment in Quebec. He found that even though the government had made efforts to formalize recruitment, more than 40 percent of the people he surveyed found their jobs through personal contacts. In the majority of cases, the personal contacts were fairly casual acquaintances, not close friends. What principle is demonstrated here

"strength of weak ties"

Explanation:

In this scenario, the principle being demonstrated is known as the "strength of weak ties". This is a principle that has been discussed by sociologist Mark Granovetter in 1973. He states that these weak ties are bridges that allow us to disseminate and get access to information and opportunities that you might not otherwise have access to. Such as these job opportunities that the individual's were able to acquire from these casual acquaintances.
