The Rise of Baito Tero: Workplace Pranks in Japan

In Japan, nearly one in four companies is expected to encounter incidents of "baito tero," a term that describes part-time employees engaging in pranks or inappropriate actions at work, often shared on social media. A survey conducted by the Tokyo-based human resources provider Mynavi revealed that 26.3% of companies reported experiencing such incidents in the past year. The term "baito tero" combines "arubaito," meaning part-time work, with "tero," an abbreviation of terrorism, reflecting the disruptive nature of these actions.

The survey indicated that certain industries are more susceptible to baito tero. Notably, 42.9% of incidents occurred in pachinko parlors, karaoke venues, and internet cafes, followed by 40% in manufacturers' production lines and 35.7% in hotels and inns. The types of incidents varied, including thoughtless social media posts, pranks, and careless handling of sensitive information. A notable case involved the ramen chain Kairikiya, which sued two part-time employees filmed playing catch with eggs in a kitchen, leading to their dismissal and a damages complaint.

In response to the rise of baito tero, companies are implementing various measures to mitigate risks. Among those that have experienced incidents, common strategies include prohibiting mobile phone use during work hours and developing response manuals. Conversely, companies that have not faced such issues are focusing on preventive measures, such as ensuring the presence of full-time employees, incorporating social media clauses in employment agreements, and providing training for part-time workers. Despite these efforts, a significant portion of companies—38.1%—acknowledged the need for measures but had not yet implemented them.

Critics argue that the phenomenon of baito tero reflects broader issues within the workplace culture in Japan, particularly concerning the treatment of part-time workers. The lack of comprehensive preventive measures in many companies raises concerns about employee oversight and the potential for further incidents. Some industry experts suggest that a more robust approach to employee management and training could help address the root causes of these pranks.

Mynavi's survey highlights the urgent need for companies to recognize the risks associated with baito tero. The findings indicate that companies that have dealt with such incidents are twice as likely to experience similar cases in the future. As a result, many organizations are prioritizing the establishment of effective management policies and training programs to foster a more responsible workplace environment.
