Is covering a woman's face obligatory, and what is the ruling on a woman working if she has to take medication for life due to health conditions?

Scholars have differed on the ruling regarding a woman covering her face from non-mahram men if she does not fear temptation, and this has been answered previously. A woman's work is originally permissible, even under normal circumstances, but she must engage in work that suits her nature and does not cause temptation. If she does not find work of this description and is in need of it, then it becomes permissible for her, provided she adheres to the regulations of Sharia: she should not go out adorned or perfumed, and she should distance herself from men as much as possible. If she needs to be close to them or address them, it should be with modesty, veiling, lowering her gaze, and not speaking in a soft, alluring manner.
