"Wage" refers to any money or valuables paid by an employer to a worker who has provided work in return for work in the form of wages, salaries, or other names. In principle, the full amount of wages must be paid directly to workers in currency at least once a month on a fixed date, and the amount equivalent to 1/2 of the payroll receivable is prohibited from seizure and can be guaranteed wages. If the business is closed due to reasons attributable to the employer, a business suspension allowance can be paid, and if the employer decides on the rehabilitation procedure or there is a reason such as bankruptcy, the worker can receive wages from the government instead of the employer through the substitute payment system for guaranteeing wage claims.
