"adequate rest" means that workers have regular rest periods, the duration of which is expressed in units of time and which are sufficiently long and continuous to ensure that, as a result of fatigue or other irregular working patterns, they do not cause injury to themselves, to fellow workers or to others and that they do not damage their health, either in the short term or in the longer term.
