asio is carrying out an initiative to prevent the damaging health effects to the brain or heart which can be caused by accumulated fatigue due to long working hours. In order to ensure proper work schedules, all employees that work 80 hours or more of overtime in a month must be interviewed by an industrial physician. The physician then checks the employee's health condition, and provides the person with advice and guidance. In this way, Casio is working to prevent health problems from overwork, and to ensure employees observe appropriate working hours.
