What is the legal ruling regarding the dues of workers who were unable to return to work and could not be reached, knowing that their dues are recorded in the company's accounts?

Effort must be made to search for the workers to deliver their dues. If, after searching, this is not possible, then donate it on their behalf to charitable causes. If their owners later appear, they should be given the choice between confirming the charity, in which case they receive its reward, or reclaiming their dues, in which case you receive the reward for the charity. The money whose owner cannot be identified should be spent for the benefit of Muslims, according to the majority of scholars.
