Explanation:

Lansbury and Prideaux (1981) discussed two dominant aspects of Industrial relations that would facilitate WPM. The first aspect is cooperation and the second is conflict.

Cooperation between labor and capital is one of the basic requirements for the functioning of modern industries and the growth of industrialization.  Here labor means workers who man the factories, mines and other industrial establishments or services. 

Conflict too is inherent in the industrial relations setup of today and it is endemic in human life. It becomes apparent when industrial disputes resulting in strikes and lockouts become frequent. The prevailing industrial unrest, the frequency of work-stop pages resulting either from strikes or lockouts, and the slowing down of production are the occasional expressions of the ever-present and latent conflict between workers and the management.
