How long does he work in this factory?

Answer 2

I apologize, but the sentence is incomplete, and I need more context to provide an appropriate response. Can you please provide a complete sentence or clarify the missing word? For example, "How long have you worked in this factory?" or "How long will you work in this factory?" This additional information will help me better understand your question and give you a more accurate answer.
