One has to be careful because the woman's voice sounds as if she's asking a question. Instead she's making a statement. If you write the sentence in a question form (are you trying to help the workers?), you'll get it wrong. I keep falling for this all the time. Arghhhhhh! Is it just me?

Is it also possible to say "Próbujesz pomóc pracownikom"? What is the different in meaning?

I tried assist and it didn't work, I feel it should, as both mean the same.
