Art 53. The duration of the daily labour of prisoners of war, including the time of the journey to and from, shall not be excessive, and must in no case exceed that permitted for civilian workers in the district, who are nationals of the Detaining Power and employed on the same work. Prisoners of war must be allowed, in the middle of the day's work, a rest of not less than one hour. This rest will be the same as that to which workers of the Detaining Power are entitled, if the latter is of longer duration. They shall be allowed in addition a rest of twenty-four consecutive hours every week, preferably on Sunday or the day of rest in their country of origin. Furthermore, every prisoner who has worked for one year shall be granted a rest of eight consecutive days, during which his working pay shall be paid him. If methods of labour such as piece work are employed, the length of the working period shall not be rendered excessive thereby.
