Career chip

Career chips are microchips implanted into people's palms which assign them a permanent career. People are given the chip for the job they're best at. According to Leela in Space Pilot 3000, it is against the law to not have a career chip implanted, or to have it removed, and the punishment for such an act is to be "fired out of a cannon into the sun". In the same episode, one of the two police officers suggests that people who take such actions are labeled as "job deserters." Despite what is presumably established in the series' pilot, there have been numerous instances when career chips have been removed and implanted without any such legal consequences, suggesting that either the laws were amended shortly after Fry was cryogenically unfrozen, or that this law is just never enforced.
