for? with? at?

[Polyester]

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?

 

[MikeNewYork]

"At" is incorrect. What do you think the other two mean?

 

[Polyester]

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.

 

[SoothingDave]

"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'.

 

[Matthew Wai]

Service this company.

I think the verb is 'serve', but I am not a teacher.

[Rover_KE]

[STRIKE]Does[/STRIKE] Is my statement correct in post #3?

This is not the first time I have made this correction.

Rover_KE Can you do the correction in post#3, please?
English is not my native language, but I studied hard.
I know I'm always making a lot of mistakes in my sentences.
Hope you can help me and correct my statements in post#3.
Thank you your great help!

Someone has already pointed out that "service" is the wrong word. "At" the company works, but "at" Tom does not.

 

[Barb_D]

You are correct when you say "with Tom" = Tom is your colleague and "for Tom" = Tom is your employer and he pays you.

 

[Matthew Wai]

do the correction

I would say 'make corrections', but I am not a teacher.
