Uniqlo Is Testing a Four-Day Work Week The retailer's pilot program in Japan would allow 10,000 employees to work 10 hours per day, four days per week.

Clothing chain Uniqlo's parent company became the latest firm to wade into the raging work-life balance debate when it announced Friday that it would let some employees clock-in just four days a week.

Fast Retailing — which also owns Theory and J Brand — said the program would allow 10,000 employees in Japan to work 10 hours four days out of seven. However, the plan does not necessarily mean workers will get three consecutive days off.

Depending on the pilot project's success in Japan it could be rolled out to the firm's headquarters and overseas, a Fast Retailing spokesman told NBC News.

The program is aimed at attracting and retaining talent — particularly women, according to the firm.

"We've got a big program at the moment, working towards empowering women in the workforce," the spokesman said. "The idea is that if you've got kids, it gives you a lot more flexibility."

Fast Retailing's decision mirrors that of other firms which have recently announced moves designed to keep workers happy by offering them a better work-life balance.

Earlier this month, online video streaming company Netflix offered employees unlimited maternity and paternity leave for up to one year. The idea behind this move, the company said, was that "continued success hinges on us competing and keeping the most talented individuals in their field."

A day later, Microsoft unveiled enhanced parental leave and other benefits for its employees.

In contrast, online retailer Amazon came under fire this week after aNew York Times story that depicted a harsh, grueling and competitive work environment that made little effort to accommodate employees' personal lives.
