> an adult worker is entitled to an uninterrupted rest period of not less than 24 hours in each seven-day period

The key word is "entitled", meaning that an employer cannot force them to work (or fire them if they don't work). The worker can choose to do whatever they want with their time, so long as they retain the right to exercise their legally permitted break.

It would be a very weird law to not allow a worker to do any work related to their job during their free time. Would that mean that a musician couldn't play music during their free time?
