Save pay stubs, attendance records, employment contracts, social insurance documents, and chat logs before leaving your job

Cost: No expense required. It takes about half an hour to save all these documents. The tricky part is remembering to do it before you leave.
In plain terms: Once you return your computer and work account, you won’t be able to access any of your pay stubs, attendance records, contracts, social insurance documents, or chat logs again. When filing for labor arbitration, you’ll still need these materials to prove your wage amount and whether you worked overtime. What you save are documents related to your own employment; do not take any company source code, client lists, or technical documents with you.
Benefit: After returning your computer and account, you lose access to all these records. While arbitration proceedings may lean slightly in favor of the employer, you still need your own evidence to prove your wage level and overtime hours.

Notes: Only documents related to your own employment should be saved. Do not take any company source code, client lists, or technical documentation with you; those are separate matters, as explained in Section 11.
