A basic characteristic of all industrial societies is large scale wage employment. People seeking wage employment and the persons providing such employment constitute two distinct groups - the workers/employees and the employers/management. The relations between these two groups ana structured; they are commonly known as employer-employee relations, labour-management relations, labour relations or industrial relations. Barring the first one, these concepts denote that the relations are collective at least on the side of employees. It is i.e. labour union that deals with the employers/management in matters of all issues that are of interest to its constituents. Hence, the relations between the two groups are organized.
