Is it permissible for a worker in Italy, who is prohibited from eating except at specific times and cannot break his fast at Maghrib time, to break his fast and offer an expiation for each day, if continuing the fast causes him severe hardship and prevents him from working?

Fasting Ramadan is one of the pillars of Islam, and it is obligatory to perform it. It is not permissible to neglect it due to conflicts with worldly matters. If fasting conflicts with worldly work and it is not possible to reconcile them, then fasting must be given precedence, and worldly work should be reduced or changed if possible, even if it means less income. "And whoever fears Allah – He will make for him a way out and will provide for him from where he does not expect." And whoever leaves something for Allah, Allah will compensate him with something better. It is not permissible to abandon fasting due to an invalid control over work hours or anything else that is not a permissible reason for breaking the fast. Expiation by feeding is not permissible for one who is able to fast.

The default is that fasting Ramadan and intending it from the night before is obligatory upon all legally responsible Muslims, except for those whom the Lawgiver has granted a concession (the sick, travelers, and those in their category). Those who perform arduous work are not in the category of the sick or travelers, so fasting is obligatory upon them. If one of them is compelled to break the fast during the day, it is permissible for him to do so only to the extent that alleviates his compulsion, then he should abstain for the remainder of his day and make up for it. The worker should seek an exemption from the oppressive work regulations, or look for another job that does not cause him to miss fasting.
