Hello, I personally think that even if the unit has such a regulation that it is forbidden to bring lighters into the venue, it was only once, and it was found at the factory gate, which did not cause serious consequences. So it is definitely illegal to dismiss you, and you can ask for compensation for your illegal dismissal. If negotiation fails, it is suggested to entrust a lawyer to apply for arbitration and safeguard rights according to law.
