I recently resigned and want to work part-time in a full-time convenience store for the time being. What should I pay attention to in my first part-time job?

First of all, ordinary part-time jobs do not sign contracts, but if they are long-term part-time, they must sign contracts, and the ID card must be copied. Don't go if you want to add a deposit. No job will ask you to pay a fund, only a few will ask you to pay a deposit. This will be boring. Just be polite when you work part-time. Do what you have to do, ask if you don't understand, and apologize in time if you do something wrong.
