The project Työläinen on Lähtenyt (english: The worker has left) is a collaboration with the artists Elena Alonso Fernández, Antton Mikkonnen, Jumpei Shimada, Elise Martineau and the Finnish company Helsinki Energy.
The Hanasaari A coal-fired power plant in Helsinki, which went into operation in 1960, was demolished in 2008 by a decision by the city council. The artists designed a memorial for the factory to pay tribute to the work in the power plant and its workers. Old machine parts and other remnants of the factory were turned into a big sculpture, that was meant to be placed in the public space. The piece is reminiscent of a plastic model, in which the objects that the workers use in their everyday life are represented. On the right side there is a hollow, shaped like a human silhouette, which gives the artwork its name.
