Wages of part-time workers are paid by the franchise store owners, but wage calculations, the issuance of paychecks and bank transfers are carried out by Seven-Eleven's headquarters.
The error affected 8,129 stores nationwide and resulted in unpaid wages totaling as much as 2.8 million yen for one employee.
Seven-Eleven will try to reimburse all the unpaid wages and established a support window to deal with the issue, although some workers are no longer employed, many records are missing and some stores have already been closed.
Seven-Eleven has recently come under fire for its treatment of franchise store owners, with issues ranging from not allowing store operation hours to be cut to unauthorized product orders placed by employees at the headquarters.
