"A collective agreement by Danish social partners in the construction sector has introduced measures to combat social dumping. The agreement, between the United Federation of Danish Workers (3F) and employer association Danish Craft (Dansk Håndværk) on January 1, obliges employers to contract out work only to firms covered by a Danish collective agreement. It also stipulates that employees must get a higher rate for non-piecework than the collectively agreed minimum." (Quoted from article)
