Sukiya, is a restaurant that is open 24 hours a day and is valuable to its customer.It was early in the morning around 5:30 a.m. when a 58-year-old female employee collapsed in the kitchen. Since there were no other staff members present, she was left unattended for three hours. The next shift supervisor who came to work before 9:00 a.m. noticed her and immediately took her to the hospital, where she was pronounced dead. The cause of death was myocardial infarction.  The shocking incident at Sukiya, a beef bowl chain, was revealed on June 2. The woman died in January of this year while working at a store in Nagoya City, where she ran the store by herself.  “Sukiya employs one-man operations to reduce labor costs and increase profit margins. There are many problems, not only in terms of safety, as in the case of the woman who died, but also in terms of excessive labor and crime prevention. Sukiya provides employees with wireless emergency buttons for emergency contact with headquarters, but the woman who died was not carrying one,” said a reporter from the business department of a national newspaper. Sukiya has been strictly enforcing the use of multiple employees from midnight to 5 a.m. since one-operator operations became an issue in 2002. In response to the death of the female employee, the company has decided to have multiple employees working from 5:00 AM onward by the end of June. The one-operator system will be abolished.
