Legal analysis: the employer has no right to collect the deposit from the laborer, which is illegal. Where an employing unit, in violation of the provisions of this Law, collects property from laborers by way of guarantee or other names, the labor administrative department shall order it to be returned to the laborers within a time limit and impose a fine of not less than 500 yuan but not more than 2,000 yuan per person. Laborers who cause damage shall be liable for compensation.

Legal basis: Article 9 of the Labor Contract Law of People's Republic of China (PRC), the employing unit shall not detain the employee's resident identity card and other documents, and shall not require the employee to provide guarantee or collect property from the employee in other names.
