Articles about high-skilled migrants in DK (Copenhagen)

Hi all Internations Cph members
I am taking up a job as a journalist at Berlingske here in Denmark, and I will cover the Danish labor market and how it fits with a more and more globalized world. I'd like to hear any input from you as to your experience with working in DK. The most common obstacles are immigration rules, difficult social life and the taxation, but Id like some input from "reality" - do you experience any other obstacles?
Finally, Id also like to hear if you have considered joining one of the Danish labor unions within your area (fx Engineers). Contact me at Protected content .
Thanks!!
