"הוא עובד בחבְרה של סבא שלו."

Translation: He is working in his grandfather's company.

[AnCatDubh]

It’s ‘for’ or ‘at’, not ‘in’. Get your prepositions straight.

[CherylHoro]

I'm American and in is ok here not completely unheard of.

[DL-Trolls]

I put "with" and feel it should have been accepted. ב readily takes on this translation in many situations.

[talyamay]

"In" is fine in South African English too. No need to be rude about people's English just because you come from a different English-speaking culture.

Nevertheless, if "for" or "at" are accepted in other cultures, they should be as acceptable here. Sure, no one shall be demerited for this choice

[EranBarLev]

"He works for his grandfather's company" still not accepted. Reported!
