Following the introduction of working-class men to the game in Northern England, clubs began paying "broken time" payments to players, due to the loss of earnings from playing on a Saturday.[15] Cumberland County Union also complained of another club using monetary incentives to lure players, leading to the IRFB conducting an enquiry. The IRFB was warned by all the chief clubs in Lancashire and Yorkshire that any punishment would lead to the clubs seceding from the union.[15] The debate over broken time payments ultimately caused the 22 leading clubs in Yorkshire and Lancashire to form the Northern Rugby Football Union. The competing unions' laws of the game diverged almost immediately; the northern body's code eventually became known as rugby league football.[15]
