What is the ruling on money that was received in full without work, given that the entity in charge of the work was the first to cancel the contracts, then reinstated them and wasted a full day of the contractors' time?

The employee deserves his salary if he reports to his work and makes himself available to his administration, even if he is not assigned any task, because a private employee is entitled to his wage by making himself available to the employer at the agreed-upon time, whether he performs work or not, "for he has done what is incumbent upon him."
