Conditions on Io are difficult - gravity is 1/6th that of Earth with no breathable atmosphere, atmospheric work-suits are cumbersome, and miners carry around their own air supply whilst working. Shifts are long but significant bonuses are paid as incentives to boost production. Explaining in an opening disclaimer, Con Am 27 is franchised to Con-Amalgamate by the League of Industrial Nations located on Earth.
