Is it permissible to give charity to poor non-Muslim workers, and is it obligatory to inform the employer of the manager’s negligence regarding workers’ rights?

It is permissible to give voluntary charity to non-belligerent disbelievers, provided they do not use it for something unlawful. Both parties to an employment contract must fulfill it, and the employee must be given his wages immediately upon completion of the work. Delaying workers' wages is forbidden. It is legislated to inform the company owner to rectify the situation, while being keen on reform and avoiding harm.
