I work in the gas station of China Petrochemical Company. I am a hired worker. Is it fair not to sign the contract? Right?

It's not fair. Are you familiar with that place? I'm not afraid if it matters. If you are not familiar with it, and he really won't sign the contract, then find another job! Your idea is very incorrect. Don't be world-weary. You are still young. At this time, people eat people, and everything is linked to interests. Be patient. High tolerance. Pay attention to your state of mind. Don't do anything illegal! ! !
