TOKYO: Japan is witnessing a record number of compensation claims related to death from overwork, or “karoshi”, a phenomenon that is increasingly afflicting young and female employees.
Labour demand, with 1.28 jobs per applicant, is the highest since 1991, which should help Prime Minister Shinzo Abe draw more people into the workforce to counter the effect of a shrinking population, but lax enforcement of labour laws means some businesses are simply squeezing more out of employees, sometimes with tragic consequences.
Claims for compensation for karoshi rose to a record high of 1,456 in the year to end-March 2015, according to labour ministry data, with cases concentrated in healthcare, social services, shipping and construction sectors, which are all facing chronic worker shortages.
Hiroshi Kawahito, secretary general of the National Defence Council for Victims of Karoshi, said the real number was probably 10 times higher, as the government was reluctant to recognise such incidents. “The government hosts a lot of symposiums and makes posters about the problem, but this is propaganda,” he said. “The real problem is reducing working hours, and the government is not doing enough.”
Kawahito, a lawyer who has been dealing with karoshi since the 1980s, said 95 per cent of his cases used to be middle-aged men in white-collar jobs, but now about 20 per cent are women.
Japan has no legal limits on working hours, but the labour ministry recognises two types of karoshi: death from cardiovascular illness linked to overwork, and suicide following work-related mental stress.
A cardiovascular death is likely to be considered karoshi if an employee worked 100 hours of overtime in the preceding month, or 80 hours of overtime in two or more consecutive months in the previous six.
A suicide could also qualify if it follows an individual working 160 hours or more of overtime in one month or more than 100 hours of overtime for three consecutive months.
Work-related suicides were up 45 per cent in the past four years among those 29 and younger, and up 39 per cent among women, labour ministry data showed.
The problem has become more acute as Japan’s workforce has divided into two distinct categories — regular employees, and those on temporary or non-standard contracts, frequently women and younger people.
Last year non-regular employees made up 38 per cent of the workforce, up from 20 per cent in 1990, and 68 per cent of them were women.
Lawyers and academics say unscrupulous employers operate a “bait-and-switch” policy, advertising a full-time position with reasonable working hours, but later offering the successful applicant a non-regular contract with longer hours, with no overtime pay.
