Remember also that at the time, breach of employment contract by the employer was a civil matter the employee would have to pursue out of his or her own pocket. Breach by the employee was a criminal matter (see the Master and Servant acts, which essentially perpetuated feudal norms into the industrial age). It was also illegal for workers to "combine" -- band together to say that either all of them would get a higher wage, or none of them would work -- and organizing such a "combination" was also a criminal offense.
Like several major sectors of the US economy at the time (and later), Britain's "revolution" was utterly dependent on coerced labor, viciously enforced by the power of the government. But some people still like to think of those times as the good old days of "laissez-faire" and government "staying out of the market".
Now, you can argue that this was a "rule of law", just a brutally repressive one which systematically granted special rights to certain classes of people, but then you're on much shakier ground.
