What is the ruling on working as a pharmaceutical sales representative who is forced to offer gifts to doctors to ensure they prescribe their medications, fearing the loss of their job, especially since doctors might not prescribe their medication if these gifts are not offered?

The company representative who offers gifts to doctors to promote his company's drugs over others is considered a "ra'ish" (mediator), who is the intermediary between the briber and the bribed. The Prophet, peace and blessings be upon him, cursed all three: the briber, the bribed, and the "ra'ish."
