What is the ruling on money earned by an engineer working as a subcontractor for his company, provided the conditions are met? And how should one dispose of it if it is unlawful? And what is the ruling on entrusting work that has an agreed-upon price to others for a fee?

An employee in a contracting company is permitted to enter bids like any other person, provided the company allows it and there is no dereliction of duty.

However, if the company does not allow it, or if his participation would lead to dereliction of duty, or exploitation of his position and company secrets, or if he has the authority to approve bids and would thus favor himself, then he is not permitted to enter.

If he did participate and performed the work without shortcomings, he must repent, but no money is incumbent upon him. If he was negligent in his work, he must return to the company the portion of the wage corresponding to his negligence.

It is permissible to obtain work and assign it to others, unless the employer stipulates that he must perform it himself.
