SMEs constitute the dominant part of the Danish firm structure (Hoff, Jens, Demokrati på arbejdspladsen), especially in the manufacturing industries - dominated by craft-based producers. Many of the findings presented in this literature do not distinguish between SMEs and large firms. But at the same time it should also be remembered, as noted above, that a large part of the Danish firms fit the SME definition. This literature review examines small business, collective representation and bargaining, working and employment conditions, arbitration procedures, size and sector considerations. It concludes with policy implications.
