"At" is incorrect. What do you think the other two mean?
Interested in Language
You are working at Tom.
You are working with Tom.
You are working for Tom.
What does the "at", "with", "for" mean in above sentences?
For "with". It means I'm working with my colleague.Working together.
For "for". It means I'm an employee who work for employer to earn the money.
For "at". It means I'm working at this company. Service this company.
Am I correct? Mike New York.
"At" is incorrect. If "Tom" is a person, you can't work "at Tom." You can work "at Walmart."
Or, as Matthew said earlier in the post I deleted:
I think 'at' would be correct if it was followed by 'Tom's office'.
Does my statement correct on post#3?
Can you point out the mistake?
