And the labor contract will specify the position, salary and other information.
See the job description for details of the labor contract (some branches are performance contract and employment notice), so these things must be signed in person and read in detail before formal employment. These things belong to the annex of the contract, which involves the specific content of the work and salary, and is also very important.
For your benefit, please note: after signing the employment notice and labor contract, you can enter the job normally. Even if there is a probation period, I have to sign this. If the probation period fails, Xinhua will terminate these labor contracts with you.
It should be noted that if you are at the business level, the management (so-called back office) must sign these! If you sign an "insurance agency contract", please note that this is only an agency relationship, not a so-called "regular employee". Most salespeople, even regional managers and business directors, are agents rather than informal employees.
