This paper compares dispute-resolution behavior at a large coal mine in Sou
th Wales at two times: when the mine was run as a conventional, hierarchica
l organization by British Coal and, several years later, when it was bought
out by the employees and converted into a worker cooperative. Synthesizing
themes from law and society, organizational theory, and alternative disput
e resolution (ADR) research, I demonstrate how shared ownership, flattened
hierarchy, and cooperative ideology impact on disputing behavior. By changi
ng from a hierarchical organization to a worker cooperative, the coal mine
increased its level of procedural justice and transformed its dispute-resol
ution behavior to rely much more on informal resolution. Using qualitative
methods, this research draws on 42 in-depth open interviews with miners and
managers.
