I never worked in Sii, but my first company was kind of similar. The biggest problem I've encountered, was basically getting paid around 3k PLN as Junior Dev while being outsourced for something like 15k PLN as Regular Dev to US/EU companies. Middleman took more than 70% of the money for themselves. The longer you stayed in the company, the more you knew how it works, so folks with 5+ years in were actually getting more fair salary, I'd say middleman (like Sii) in their case took around 10-20%, which is quite resonable.
I have the feeling that a union this guy formed aimed to cut down the fee for any new joiners or people not aware how much they were being ripped off.
