Worker-priest
Worker-priest (French: Prêtre ouvrier, Prêtres au travail) was a missionary initiative by the French Catholic Church in particular for priests to take up work in such places as car factories to experience the everyday life of the working class. A worker-priest was any priest who was "freed from parochial work by his bishop, lived only by full-time labor in a factory or other place of work, and was indistinguishable in appearance from an ordinary workingman".
