Explaining the Difference Between "Working In" vs "Working For"



Great observation! Both "working in" and "working for" are correct, but they have slightly different uses depending on what you want to emphasize:
- "Working in":
- Focuses on the location or field of work.
- Example: I've been working in this company for five years.
(Highlights being inside or part of the company.) - Example: She works in marketing.
(Refers to the field/department.)
- "Working for":
- Focuses on the employer or organization.
- Example: I've been working for this company for five years.
(Emphasizes employment or service to the company.)
In your friend's sentence, "working for this company" is more common and idiomatic in English, especially when referring to employment. "Working in this company" is less natural but can be acceptable in some regional varieties or to emphasize being part of the organization. I hope this helps!
