Hey can you help me understand these two sentences??

1. I don't see a future for this job.
2. I don't see a future with this job.

I guess both of them are grammatically correct but there's a subtle difference between them.

I think the first one means this line of work has no future even if you change your company and the second one, I think it means I don't see a future for myself if I keep working at this company but I might have a bright future if I change my company. I could be wrong so please correct me if I am.

Answer

You are correct, both sentences are grammatically correct but have subtle differences in meaning:
1. "I don't see a future for this job.": Implies that the job itself (or the line of work) has no prospects or potential, regardless of the company.
2. "I don't see a future with this job.": Implies that you don't see a future for yourself if you continue in this specific job or with this company, but you might see potential if you switch companies.
