A postal worker who said she was bored with work stashed away 29,000 undelivered parcels and letters over the past two years.

The 23-year-old woman in Mitoyo, Kagawa Prefecture, admitted failing to deliver the items, declaring she was "just fed up with the job," Japan Post Co.'s Shikoku branch said Monday.

Her inaction represents a record of sorts: It is described as the largest volume of deliberately undelivered mail since the company was privatized in 2007.
