Breaking party discipline in parliamentary votes can result in a number of consequences such as not being promoted to a cabinet position, and losing other perks of elected office like travel. Disagreement with the party caucus may lead to a member leaving the party to join another parliamentary caucus or become an independent, which is known as crossing the floor. With party discipline, there is an unwritten rule that pressures parliamentarians to compromise their beliefs if they conflict with the decisions made by the rest of the party.
