What is the content of the general property security labor contract?

The contents of a property security contract generally include: the validity period of the contract (i.e. the employment term), work contents, wages and benefits (including the reward and punishment system), social security insurance, supplementary agreements of general companies, etc. Each local labor bureau has a labor contract format stipulated by the state, but the content of the supplementary agreement is different (this is the supplementary content of the enterprise).
