I had a chance to visit Norway recently, and this was something that a tour guide impressed upon us about the culture; she gave an example of a restaurant in town that was caught skimming pay, and it wasn't just a union representing restaurant workers they heard from; they found themselves unable to find someone to repair plumbing or their storefront (the plumbers and glaziers wouldn't work with them), and their ingredient supply chain suffered (truck drivers told them to make their own 3AM trip to stock up).
