In Japan, viral ‘baito tero’ workplace pranks plague businesses
Psychologists say the quest for online clout is driving the rise in ‘meaningless’ workplace pranks, also known as part-time job terrorism

This year, nearly one in four Japanese companies are expected to fall victim to baito tero, a term describing part-time employees performing pranks or stunts at work to post on social media, according to a new report.
The study by Tokyo-based human resources provider Mynavi, conducted in December and released in late January, revealed that most of the incidents came to light because the perpetrators shared their antics on social media.
Karaoke bars, hotels, restaurants, convenience stores, supermarkets and factories are most at risk of baito tero – a phrase that combines arubaito, a loanword derived from the German for “work”, with an abbreviation of “terrorism”.
In November, ramen chain Kairikiya sued two part-time employees who were caught on camera playing catch with eggs in the kitchen of a branch in Sakai City, Osaka prefecture.

The company said in a statement that the incident occurred after hours and no food was served to customers. Still, both workers were fired and a damages complaint was filed with local police. Kairikiya said it had since tightened employee guidelines and would be seeking damages.
