Manufacturies The guilds controlled the methods and hiring practices a business could use, limiting entry into the labor force and demanding that only highly skilled and certified (by the guild, naturally) craftsmen perform certain tasks. Increasingly, industrialists left the cities and founded new sites of innovation, free from the exacting standards and high wages of the guild masters.
