What is the ruling on eating at the workplace when there is a girl dressed inappropriately and exposing her 'awrah, and is it permissible to remain until the meal is finished, or is it obligatory to alternate eating with moving away from her?

The temptation of women is among the greatest and most dangerous temptations for a Muslim. It is not permissible to remain with a girl who causes temptation. It is advised to find another job to avoid her, and if that is not possible, one must lower their gaze and keep away from her at all times to avoid temptation.
