This article discusses a particular type of social conflict, which is NIMBY (Not In My BackYard) syndrome. It has been very well studied and described by American sociologists. Although NIMBY syndrome has been present in Poland for relatively short time it is de?nately a sign of organising different types of local communities against interfering processes. Although usually depicted as negative phenomenon in most con?icts in the region of lodz it has proved to increase local activity, created new channels of social communication and leaders. It can be also stated that NIMBY syndrome has its source in omitting or separating local community from decision-making procedures and insufficient information on affair/venture being planned. The research revealed that NIMBY protests were characterised by violent beginning, significant time of existence and appearance of sudden, violent and often abrupt reactions of community during time of the con?ict. Dominating forms of activity were petitions and letters being written form. Another activities covered blockades, manifestations, demonstrations and destruction of construction machines or construction site itself. Most frequent form of extinguishing the con?ict was arbitrage which is forcing administrative decision against community which resulted in increasing distance between the community, local authorities and investor.
