China has the most chilled employees, a new report has found, while Japan's famously stressed-out staffers are, well, stressed.

Randstad's latest Workmonitor report found that 44 percent of employees in Japan found it hard to let go of work even while on holiday, followed by Malaysians at 36 percent and Singaporeans at 32 percent.

At 27 percent, Indians were moderately distracted by work. New Zealanders, Australians and workers in Hong Kong were more relaxed at 25 percent, 24 percent and 19 percent respectively, while just 15 percent of Chinese workers worried about work during their vacations.

"Japanese are in general very serious about their work and dedicated to their employers, especially for those in permanent roles," Ikumi Maekawa, communications manager at Randstad Japan, told CNBC.

Clocking long hours and working hard helps the long-term career development of Japan's workers, and they tend to stay in one company longer compared to other Asian cultures, Maekawa added.

And with greater digital connectivity, comes greater work responsibility, Randstad found. With smartphones, connected devices and communication apps that significantly decrease the cost of being contactable overseas, it can be harder for employees to unplug from the office. There were 269 million connected devices and 85 million active smartphone users in Japan at the end of 2014, according to an IHS report.

Meanwhile, in China a highly mobile workforce helps keep workers from suffering too much job-related stress while out of the office.

"Chinese employees are more active when it comes to switching jobs to develop their careers and improve their working conditions," said Maekawa. "Therefore, in order to retain employees and keep them happy, employers in China are happy to provide space to their employees and let them enjoy their holidays."

Employers in other countries could learn from China, because Randstad found that switching off from work improved productivity and boosted employee morale.

"Business leaders should be clear on how switched on they expect their staff to be when they're not at work," said Michael Smith, Randstad country director for Singapore.

Certain job roles with higher client interaction would need to respond around the clock, while it might be acceptable for others to reply to an email on Monday morning, he added.
