"We see systematic and well-planned cheating, made possible by professional arrangements where law firms tailor models," said Kim Söderström, chairman of the Swedish Construction Union, in a press release.
He believes that Swedish agreements and Swedish legislation are being undermined.
"It not only threatens the construction industry, but, in the long term, our entire Swedish model."
Last year, Swedish Construction Inspection, an independent unit within Byggnads, carried out 128 audits of subcontractors, of which 64 were completed and 64 are ongoing.
Among other things, they show that construction companies both falsify documents and pay wages that are lower than those agreed upon collectively.
