This article has an idiotic title and, like so many other reports on Fukushima lately, contains a hefty dose of alarmist bullshit, but it also brings up a very valid issue: that of Tepco trying to escape its responsibility and generally pinch pennies by using subcontractors instead of employees, both in its cleanup efforts and in its daily operations.
Job offers come not from TEPCO but from Mizukami Kogyo, a company whose business is construction and cleaning maintenance. The description indicates only that the work is at a nuclear plant in Fukushima prefecture. The job is specified as three hours per day at an hourly wage of 10,000 yen (about US$122). There is no information about danger, only the suggestion to ask the employer for further details on food, lodging, transportation and insurance.
Those who answer these offers may have little awareness of the dangers and they are likely to have few other job opportunities.
