About 20 percent of working men and women who responded to a recent Internet survey said they would like to work under a performance-based system without overtime pay, as proposed by the government.

In the survey of 1,000 people working in various fields as employees, temp staff, managers and business owners, conducted by the Japan Management Association in June, 25 percent said they would not want to work under such a system, while 56 percent said they did not have a preference or were unsure.

The so-called white collar exemption, part of Prime Minister Shinzo Abe's growth strategy to reinvigorate the economy, proposes that professionals earning ¥10 million or more annually be paid based on their performance with no overtime pay.
