This Statute of Laborers was again re-enacted in 1360, with a clause allowing work in gross, and forbidding "alliances and covins between masons, carpenters, and guilds." Work "in gross" means work by contract, piece-work, thus made expressly lawful by statute in England in 1360, but still objected to by many of our labor unions to-day. The provision against alliances and covins was extended to cover trades-unions, their rules and by-laws, as well as strikes, which were also considered combinations in restraint of trade. Now this was never law in this country. There was a very early case in Pennsylvania, while it was still a colony, and there were others in the States soon after, which held that the Statutes of Laborers were never law in America. Our statutes early authorized trades-unions, but without this there is, I think, no American case where either a trades-union or a simple strike was held to be an unlawful combination. It was these early statutes which gave rise to the law that existed until the nineteenth century in England, that both strikes and unions were unlawful; a strike because it was usually a combination to raise the rate of wages, which was in theory fixed by law. Therefore, a strike was a combination with an unlawful aim, consequently a conspiracy. The logic is simple; and in the same way a trades-union was certainly an alliance between skilled workmen, and as such forbidden under the Statute of Laborers, besides being a combination in restraint of trade.
