"Inverted burden of proof" widely exists in the field of labor law. Articles 6 and 39 of the Labor Dispute Mediation and Arbitration Law, Article 13 of the Supreme People's Court's Interpretation on Several Issues Concerning the Application of Laws in the Trial of Labor Dispute Cases, Article 9 of the Supreme People's Court's Interpretation on Several Issues Concerning the Application of Laws in the Trial of Labor Dispute Cases, Article 6 of the Supreme People's Court's Provisions on Evidence in Civil Litigation, Article 2 of the Notice of the Ministry of Labor and Social Security on Establishing Labor Relations, wage payment vouchers, social security. The employer may be required to bear the burden of proof.
If you want to fully protect your legitimate rights and interests, I suggest you look at the Labor Law, the Labor Contract Law, the Regulations on the Implementation of the Labor Contract Law, and the Social Insurance Law, so that you can know in what ways the employer has violated your rights and interests, which will benefit you for life.
If the employer infringes on your legitimate rights and interests, pay attention to collecting evidence. This is very important if there is arbitration or litigation in the future.
Any evidence that can prove that you have a labor relationship with the employer can be used as evidence. No, I'll teach you a trick. Since it is a small company, the legal awareness should not be particularly strong.
Tell the legal representative of the company that since I don't agree to leave, I don't have to leave, but you can always approve a few days off. You write a written explanation, because you have something to ask for leave for a few days, and write down the employees in a certain department of a company. Ask him to sign and keep the original. If the company asks why you want to sign it, you can say that I am a buddy and I asked my boss for leave to go home. After agreeing, I went home for a few days. After I came back, the employer said that I was absent from work for several days in a row and was removed from the list, which caused great losses to the company and my salary was not paid. Therefore, I must have this note. It's not that I don't trust the company I need a guarantee. If the boss is not the legal representative of the company, it is best to stamp it, otherwise it is possible that the boss will be copied by the legal representative. This boss is just a senior employee invited by a legal representative.
With this article, you can propose to terminate the labor relationship at any time. See Article 9 of the Interim Provisions on Wage Payment and Article 50 of the Labor Contract Law for the time of wage payment when the labor contract (or labor relationship) is dissolved. If the payment is not made on time, it can be handled according to Article 3 of the Measures for Economic Compensation for Violation and Termination of Labor Contract 10 or Article 85 of the Labor Contract Law. The difference is that the former can claim directly, and the latter can claim only after the labor department orders it not to pay.
