Of course, the main contract is the best The main contract has HR indicators, the personnel occupation and salary preparation are signed with PICC P&C company, and the salary and benefits are good.
The local version of the contract was signed with the branch company, which did not account for the salary establishment of PICC P&C company, and the treatment was almost inferior.
Dispatch is even worse, there is no salary preparation, and it is financial labor expenditure, and wages and benefits are even worse.
Labor contracts are generally short-term non-fixed employment or re-employment after retirement, all of which are agreed wages and have no reference.
See if it's ready when you go in. If you have made it up, it is the general contractor. Of course, it is best to sign a general contract. If it is not compiled, try to sign the land version contract.
I hope it helps you. If you think it's good, give some points.
