4. Concepts, variables and classifications

4.1. Definitions of the main concepts and variables

Work stoppages The statistics cover labour disputes, or work stoppages, of at least one day's duration. The number of disputes per year is computed from the number of trade union federations or confederations that have had groups of employees involved in a work stoppage. Strikes that are discontinued and later resumed for the same reason count as one strike unless where the interruption lasts more than two months. A dispute resumed after more than two months counts as a new strike. A dispute that occurs one year and continues the next is included in both years, i.e. as two strikes. There are two types of work stoppages, strike or lock-out. A work stoppages defines as a temporary work stoppage starting up of a group of employees (strike) or one or several employers (lock-out) to force a demand. following types of strikes are covered: legal strikes, illegal strikes, sympathy strikes, political or protest strikes, general strikes, work stoppages started by employees,Lockout som konfliktmiddel er arbeidsgiversidens svar på streiker. En lockout innebærer at arbeidstakere utestenges fra arbeidet inntil partene er blitt enige om en måte å løse uoverensstemmelsen på.

5.2 Non-response errors

The statistics are based on a census, thereby avoiding uncertainty associated with sample variance and non-response associated with sample survey.

5.3. Sampling errors

The statistics are based on a census, thereby avoiding uncertainty associated with sample variance and non-response associated with sample survey.

Measurement errors can mainly occur because the respondent misunderstands what is included in and consequently reported in each column on the form or because it is very difficult for the respondent to find the information requested. All variables collected and that, directly or indirectly, are included in released statistics are checked, either in logical controls or by absolute limits for what is considered valid. If important data are missing in the received reports, the data are obtained either by returning the form, by a phone call to the respondent or by imputation.
