"Mein Kollege handelt mit Produkten."

Translation: My co-worker deals with products.

[Curran919]

In Switzerland, I have found Kollege to mean nothing BUT friend...

[Daalianer]

I am Swiss. You are right, it can mean the same, but I myself differentiate between "Kollege" and "Freund". To me "ein Freund" is someone who is closer or more familiar to me than "ein Kollege".

What is wrong with coworker as a single word?

So, what is wrong with "My co-worker handles products"?

[lesliedawne]

I believe "handeln mit" can also be translated as "deal IN" - and that both versions should be accepted.
