After the Fall, men have a tendency to fall into mechanical work, to become a clog in production. Saint Peter says he's going to fish. Work can be an escape from God, when that work doesn't develop man. There was no satisfaction. Work can be an escape from God, for man is afraid of God, afraid of letting go of their proud securities.
Men often look for salvation in a small project.
Saint Joseph was afraid of his unique vocation, willing to leave Mary. Saint Peter says to Christ to leave him alone because he's a sinner. If work is an escape from God or from love, it is never truly productive or healing. Man grows when he uses the work for the benefit of another. In the New Testament, the vocation of the man is to transform the world for Jesus, so that it will become more Christ-like.
