The notion of work in the Emile of J.J. Rousseau

According to Rousseau, work teaches us wisdom about time and a sense of selfness and reality which protect everybody from imagination, passions and society harms. "The worker does not dream" will say S.Weil. What notion ofwork is here implied? Nothing which could be later found in classical Political Economy, Marx or the socio-economy. Rousseau indeed thinks work is an access to economy, but his economy remains under the rule of the usevalue. It is a qualitative economy.
