Matsuri Takahashi was 24 when she died. She took her own life after doing more than 100 hours overtime a month at a large advertising company in Japan. She was a victim of karoshi - dying as a result of overwork. It’s a phenomenon that’s well known in Japan where stories of employees working ridiculously long hours – sometimes until four or five in the morning - are common. The government has introduced a new law to limit overtime, although critics say it doesn’t go far enough and the whole working culture needs to change. Working long hours doesn’t necessarily mean more work gets done, so elsewhere, a company in New Zealand has reduced hours without cutting pay. Staff are given a day off each week if they can get five days’ work done in four. Should we all be doing this? Presenter: Nick Holland Reporters: Jamie Ryan and Mariko Oi (Photo Credit: Getty Images)
