Career chip

Career chips are microchips implanted into people's palms which assign them a permanent line of work. The label of each individual chip corresponds to the job that the receiver is best at. According to and Smitty in "Space Pilot 3000," the career chip is mandated by the law, and anyone who rejects it will be labeled a "job deserter" and "fired out of a cannon into the sun". Despite these warnings, there have been numerous instances in which career chips have been removed without any such legal consequences. Two possible in-universe explanations are that the laws surrounding the career chip were amended shortly after was cryogenically unfrozen or, more likely, that these same laws are just never enforced.
