The firm portrayed the fall in productivity in a chart in which shows that while in 2004 the plant turned out 24 vehicles per worker, in July 2009 that figure was just two vehicles per worker.

The announcement noted that this situation is occurring after the crisis suffered at the beginning of the year, when the murder of two Mitsubishi workers led to the takeover of the installations for more than 120 days.

When that problem was overcome, the plant resumed its activities on April 13 with the commitment of the unions to produce at least 60 vehicles per day, but output had only reached 33 vehicles per day, the announcement said.

The firm has 1,412 workers on its payroll.
