Note: SD, standard deviation. Defined as the percentage registering rarely getting sufficient sleep. Bricklayer’s labourers in Danish construction work are workers who make sure bricklayers have all the materials they need and that the work site is ready to work and is clean and tidy and also plan work ahead. This is a very traditional organization of bricklaying.
