Definition: Slack work for technical or economic reasons
A slack work for technical or economic reasons includes difficulties such as plant breakdown or materials shortage (see also "Labour dispute"). Contrary to lay-off, a person in slack work for technical or economic reasons should have a formal attachment to his/her job. This formal attachment should be determinated in the light of national circumstances, according to one or more of the following criteria:
(i) the continued receipt of wage or salary;
(ii) an assurance of return to work following the end of the contingency , or an agreement as to the date of return;
(iii) the elapsed duration of absence from the job, which wherever relevant, may be that duration for which workers can receive compensation benefits without obligations to accept other jobs.
