A trade union is defined as a workers’ organization constituted for the purpose of furthering and defending the interests of workers. For the purposes of promoting international comparability of the statistics presented in ILOSTAT, trade union membership refers only to union members who are employees. That is, it excludes union members who are not in paid employment (self-employed, unemployed, retired, etc.), unless otherwise stated in the notes.
Workers covered by collective bargaining are all those workers whose pay and/or conditions of employment are determined by one or more collective agreement(s). Collective bargaining agreements refer to all agreements in writing regarding working conditions and terms of employment concluded between an employer, a group of employers or one or more employers’ organisations, on the one hand, and one or more representative workers’ organisations, on the other. Collective bargaining coverage includes, to the extent possible, workers covered by collective agreements by virtue of their extension, as well as workers covered by collective agreements concluded in previous years but still in force.
A strike is a temporary work stoppage carried out by one or more groups of workers with a view to enforcing or resisting demands or expressing grievances, or supporting other workers in their demands or grievances.
A lockout is a total or partial temporary closure of one or more places of employment, or the hindering of the normal work activities of employees, by one or more employers with a view to enforcing or resisting demands or expressing grievances, or supporting other employers in their demands or grievances.
The concept of days not worked as a result of strikes and lockouts refers to the total number of working days during which work would normally have been carried out by each worker involved had there been no stoppage.
The concept of workers involved in a strike or a lockout covers those directly or indirectly involved at any time during a strike or lockout, whether the involvement was for the full duration of the strike or lockout, or only part of it. Workers who are unable to work as a result of the secondary effects of strikes or lockouts should not be included. Workers directly involved in a strike are those who have participated in the stoppage of the work, whereas workers indirectly involved in a strike are those who were unable to work due to a strike. In the case of lockouts, workers directly and indirectly involved refer respectively to the “employees of establishments involved who were directly concerned by the labour dispute and who were prevented from working by the lockout” and “employees of the establishments involved who were not directly concerned by the labour dispute but who were prevented from working by the lockout”.
Employees refer to wage and salaried workers as defined by the International Classification of Status in Employment (ICSE-93). Employees are all those workers who hold “paid employment jobs”. These are jobs where the incumbents hold explicit (written or oral) or implicit employment contracts which give them a basic remuneration that is not directly dependent upon the revenue of the unit for which they work (this unit can be a corporation, a non-profit institution, a government unit or a household).
