What is the connection between the work of a person and the qualities of his personality

What is the connection between the work of a person and the qualities of his personality, the attitude of other people towards him?

Living in society, each person must work, do his own amount of work for the benefit of all other people. Each of us has our own social function. Children go to school, students master their specialty, adults work in enterprises or government agencies. Society is like a well-coordinated mechanism in which every cog is important. If someone is messing around, the mechanism will go wrong. This will manifest itself in economic failures, deterioration in the quality of life. Relations between people will also be strained, there will be no customary trust.
