Top 10 at-work pranks that get employees fired in Japan

Summer wave of "part-timer terror"

Part-time workers at convenience stores and fast-food outlets in Japan have been pulling stunts at work and posting photos of their pranks on twitter, Facebook and blogs. Embarrassed companies are issuing apologies and closing shops to clean up equipment and restock shelves tainted by the so called  "baito tero" – "part-timer terrorists."

Most of the prank pics have ended up on twitter which is being referred to by some as the "idiot detector".

The pictures of pranks that occurred in August prompted web searches for previous posts of employee’s at-work pranks. The earliest post – found so far – occurred in March.

The outbreak of stupid acts seems to have coincided with the high school vacations, when students are able to work more hours. Spring break is at the end of March, and the summer break began at the end of July and ended September 1.

Commentators and editorials are offering advice about curbing the antics.

They point out that employees who post such photos do not reveal their real names, and have stated they believed the posts were unimportant.

Some advice from the media:

  • Businesses should explain the consequences of unapproved posting of business photos on websites.
  • Staff should be reminded the posts have a potential global audience.
  • During job interviews, the use of social networks should be reviewed.
  • The use of personal smartphones during business hours should be banned.
  • Including business names in any online posting by employees of the given business should be prohibited.
  • Employees who violate the new rules should be strongly reprimanded.
