Yes, the work permit is practically automatic within Schengen, and not even needed between Nordic countries, but it is not an absolute right: persons from another Schengen country may legally be barred from entering (typically, this is outcome of repeated/aggravated criminal convictions). This is possible even between Nordic countries (consider Juha Valjakkala / Nikita Fouganthine who we get to keep in Finland as Sweden understandably does not wish him to enter).
