If a worker engages in work outside of the workplace during all or part of their working hours and it is difficult to calculate working hours, the number of hours worked is deemed to be the prescribed working hours; provided, however, that if it would normally be necessary to work in excess of the prescribed working hours in order to carry out that work, the worker is deemed to have worked for the number of hours that, pursuant to the provisions of Order of the Ministry of Health, Labour and Welfare, it is decided would normally be necessary to carry out that work.
前項ただし書の場合において、当該業務に関し、当該事業場に、労働者の過半数で組織する労働組合があるときはその労働組合、労働者の過半数で組織する労働組合がないときは労働者の過半数を代表する者との書面による協定があるときは、その協定で定める時間を同項ただし書の当該業務の遂行に通常必要とされる時間とする。
