Reasons for not returning to work: Those who meet the starting conditions need to apply for a report on returning to work. Enterprises need to prepare temperature measuring gun, disinfection facilities, disinfectants, disposable gloves, masks, personnel registration reports, etc. After returning to work, there is no or limited catering, and it is impossible to support the operation of a regular store only by taking out food, and it is impossible to guarantee the normal operating expenses of the enterprise. The dining hall's passenger flow can't meet expectations, so it's better to continue to close down after opening. A large number of employees have not yet gone to work, and the staffing of each position is not in place, so it is impossible to complete production and service work. Some cities do not allow catering enterprises to resume work now, and restaurants will be the last enterprises to allow them to resume work. The biggest worry of catering investors is that in case of COVID-19 infection in the store, they can't escape the responsibility of poor supervision.
